I am 44 and for years have been taking all the natural vitamins to help prevent all the symptoms of menopause, e, b6, b12, c, cal/mag/zinc, ginseng, guarana, a multi, some 17 a day. I also have taken bio-change with black cohosh and black cohosh, also for years, seemed to do the trick, although I did get hot flashes every once in a while I could live with that. Last week my mother told me she read up on black cohosh that it could cause cancer and should only be taken up to 6 months, I have been taking them for years, some 540 mg. In one and 40 mg in the other, my mom told me I shouldn't take them. Not a couple days later after I stopped the two vitamins it started big time, I now get hot flashes, some 10 or more a day, and night sweats, I haven't gotten my period for over a month and I am so tired, fuzzy headed, I have bad pains in my neck & back, I can't seem to do every day things, I just want to sleep. I also have very bad allergies all year round, once they are triggered it goes into a sinus infection, they now have seemed to worsen. I have had 3 sinus surgeries and take daily advil cold & sinus daily and an allergy drug called zyrtec. The zyrtec seemed to help for a very long time until now. I am a very active person and this is killing me. I'm not sure if this is caused due to stopping the black cohosh all of a sudden. I look to see if there might be any other natural vitamin and most, if not all, have black cohosh in them. I am out of work and feeling this way I don't even have the energy to look for another job and I have no health insurance so I can't even go to the Dr. I'm hoping someone can tell me if they take natural vitamins and which one might help. I also have no idea of how much of what vitamin can help, one said take 400 mgs of this or 200 mgs of that so I have no clue as to how much and what to take. I looked into soy which I read can help and then read they are finding that isn't good for you either. Any suggestions would be greatly appreciated I am at a loss. Thank you very much~ kat
