My doc prescribed 50 mg Naltrexone for "binge eating disorder". I took the first tablet Sunday night, within an hour I had "feel-good thoughts", mental changes, restlessness and severe nausea. I was afraid I wasn't going to wake up! Then, in waves I would have extreme nausea, followed by chills, and profuse sweating. This went on for about 3 days and still I have indigestion and bloating. Was this an allergic reaction? Or was this just a toxic dose?
