Kathysway, sorry you find yourself in this situation. Having taken several of these drugs and having read extensively about the side effects and the experiences of others, it seems there is no rule of thumb regarding symptoms.. Every person reacts (or does not) differently and every drug can affect you in surprisingly different ways. My approach was to give one drug a try and see what happens. If it's no good, on to the next one. There are 5 that a post-menopausal woman may take, but do consult your doctor. If all are intolerable, then at least you know you gave the drugs a shot. One of them did prove to be acceptable to me after some miserable failures that produced no lasting effects. Good luck to you.
