I can't stop drinking fizzy pop it's the only thing keeping me awake as I near the end of my pregnancy I'd say I tend to have a small shop bought bottle (I run out on my lunch) probably a day at minute and have done for last about 3 week. I always get diet or Pepsi max. Any other ladies do this. I feel like a terrible mother already but I haven't drank or smoked my entire pregnancy (I did pre pregnancy) so I think we'll surely this small fizzy pop bottle can't do any harm. I also don't drink caffeine (there's none in house as husband can't drink caffeine)
