raynaud's syndrome
"I have been taking 1 tablet of Nifedipin(e) XL 30 mg ER for almost 2 years. I stop in the summer and start again when it gets cold and that works well for me. I haven't had any of the side effects such as rashes or headaches but I have been very tired and now that I think of it, it's probably because I've been taking it during the day instead of at night like I used to. The only problem with that is if you like to have a cocktail and for times like that I just don't take it."
