I Do Not Feel Well. I Was Taking Tamoxifin For

I do not feel well. I was taking tamoxifin for about 4 years. Have stopped taking it because felt awful. Feel like I get hit above my stomach, feel like I'm going to throw up and then I get goose bumps on my right arm. My dr.. has me taking 20 mgs of Citolaprain. Doesn't seem to be helping. I just feel awful and I'm so scared. I can't stay home by myself. Dr. has me going to a counselor. She doesn't get it either. email is YYYY@YYYY I feel horrible
