Yes or no?

It's a bit of a rough ride, this pregnancy. Having gone straight from being sick to constant indigestion I am also suffering with lack of sleep as my joints have got very painful and keep waking me up at night. I'm also finding that if I need to spend any length of time on my feet - even just a little while to do something like cook a meal - then I need to wear support bandages on my lower legs to keep from going light headed. I can't walk far or fast, but they have been very nice to me at work this week. I got to spend the whole day sat at a table at the front of the shop making the models for the Easter Inspiration display. Two painted ducks, one covered in the delightful glue and tissue paper concoction we call decoupatch and a Humpty-Dumpty made from a large brown maché egg. He looks jolly good, though I say so myself.
At least I finally got to see a doctor this week. I have been referred for physio for my joints, but that will all depend on the waiting list. All I want to do is to be able to sleep comfortably! I have been given some cocodamol to help, but I'm rather nervous of taking it, despite being assured it's perfectly fine.
Is it? I was given pure codeine in my last pregnancy near the end of my first tremester for headaches, but found out on line it was not safe except in the second. I've looked again and the advice now says never in the second and emergency use only. Also not ideal in the third as it makes the baby drowsy and the baby can become addicted if used regularly.
The doctor said it was fine, but the leaflet that came with the meds is quite specific - do NOT use if pregnant or thinking of becoming pregnant. Help! I'd just like to be able to sleep at night and not feel that people with acid covered red-hot pokers are investigating all the joints in my hips and legs.
It's Joseph that's the biggest loser in all of this. I'm permanently tired, bone achingly weary. I can't play with him like I want, my energy levels are too low and I can't sit on the floor for more than a few minutes without terrible pain and then I can't get up again anyway. The weather is either cold, rainy or both so taking him to the park so I can sit on a bench and he can run off his frustrations is a rarity. By the afternoon we inevitably end up snuggled on the sofa with Netflix on. I guess it's better than nothing, but I do have the nasty habit of falling asleep in the middle of whatever we're watching, only to have him poke me and tell me it's finished and can he have another?

Cocodamol isn't the only conflicting pregnancy information out there. There's lots.
Alcohol, for example. None at all is the standard advice, but lots of science people are chiming in saying that a little is ok, even moderate drinking, only to be followed by people who say "oh no it isn't" and then the first lot say "oh yes it is!"
As for eggs.... well, you don't eat raw or runny eggs because of the risk of salmonella. They're good at trumpeting that one about. Except - if you buy fresh eggs in the UK with the little red lion lasered onto it then they're guaranteed to be salmonella free. Also salmonella itself isn't known to harm the baby, but pregnant women are likely to be sicker because of our lowered immune systems. Not that you're at much of a risk of catching it in the first place if you buy the right sort of eggs.
Exercise. Some say none at all, others are equally authoritative that sitting around on your rapidly swelling bum all day is not on. It's not fat, it's oedema. 
The Royal College of Obstetricians and Gynaecologists (try saying that when you've had a few, it's hard enough to type it sober!) got into a bit of hot water last year by publishing a list of things pregnant women should avoid and it was rather... well... to be frank, it was rather stupid. It listed things like moisturisers (umm... most pregnant women rub pints of the stuff just on their bump on a daily basis) and shower gell! Now, I'm one of these people with very sensitive skin and I can't shower as often as most people or I would turn into the itchy skin flake monster and then blow away in the next puff of wind, but even I will not give up the use of shower gell, especially as fragrances also make the list.
Also I am not allowed to buy any new furniture or cook wear, especially if it's non stick. I should not eat any form  of processed food, especially if it comes in a plastic pack. I should avoid any form of household chemical (woo-hoo, no cleaning!) and no pesticides. That's ok, we have a cat and she eats all the flies. Except that's not ok as cats are disease ridden bags of nastiness who harbour toxoplasmosis (and a general deep seated loathing for all and sundry, but that's not comunicable) which can harm your baby - but only if you're infected for the first time when pregnant. We've had the fluffy pain the ass for nearly nine years now and long before I was pregnant with Joseph I was having to empty litter trays and generally getting scratched for all my attempts to be affectionate. I probably got my first dose many moons ago and am now probably totally immune. Still, I have been advised to steer clear of poop and sick from the moggy so someone else has to clear it up. He he.

And, as far as I can tell, the most important dietary advice? Don't catch listeria. That's the one that really can harm the baby, but it tends not to get so high up the page as salmonella. That's the one you can get from not re-heating food properly and apparently it likes to grow on cooked rice. It also loves pate, so there are some things I am being jolly careful with.
Ironically it did result in an older lady sighing at me once. At a Christmas event, I had swapped my starter of several different kinds of pate (and it had been out of the fridge for hours!) for cream cheese.
"We didn't have all that in MY day." she said.
Yes, trust me, you did. You had listeria all right, but the risks weren't so well known, that's all. Some of the advice in pregnancy is silly, but some of it is very sensible so please stop saying that to pregnant women, it's one of the reasons less of us die now.
