So, did the doc tell you about the caffeine withdrawal headache you are going to get from stopping the caffeine? Stop it slowly my dear FFM! Take this from someone who has been there done that! You know...
MSAcorn has a great idea!
I was once told to stop all the caffeine due to fibrocystic breast disease. Well, it didn't make any difference at all. Not one single bit. I love my coffee (and my chocolate!)
You can do it Kay! I won't lecture you on the smoking...
Have a great trip!
