Well Patty,

I will talk for myself here...

Coffee and Chocolate make my PN bad... I mean, BAD. I know that if today I drink a cup of coffee, I will be having a nasty evening and 2 days of horror...
What I do is take them under my own risk... I mean, if I really, really need to take coffee or choco, I do, but I know I will need to stay at home for the next 3 days taking care of my symptoms...

Good luck !
