You stated you took vitamins, most people dont know that the majority of people who take vitamins dont get the nutriants from them due to intestinal parasites. This could be the cause your stomach pain
also. When you drink alcohol
, it depletes your vitamins anyway, so, if you have alot of parasites (everyone does) no vitamins are getting to your system. Go to a homeopathic Doctor, they can test you for these little buggers. Also, google thiamine deficiantcy signs.
