diet soda? contractions?

Anyone out there have an occasional (or not, I'm not judging!) diet soda?  If so, do you notice if it causes BH? 

i drank alot of diet coke ... i noticed i would get crampy at the end of the day.. if i didnt drink a non-caffine drink for every caffine drink i drank.. does that make sense?.... so 1 diet coke = 1 water

I drink about 3 diet cokes a day.  I'm 30 weeks pregnant, never had a braxton hicks contraction that I know of.

Never did for me...but I perfer caffiene free diet soda if I have one!

I used to drink diet coke all the time but i never had any BH with them
