I just got out of the psych ward of a hospital two weeks ago, I was in there because I just lost my mom & had been taking pills for a number of years. My drug of choice was xanax and percoset. I was prescribed EffexorXR 75mg and gabapentin 300 mg. Right now my body is going crazy. I have no energy, I constantly have a headache, Im dizzy, cant concentrate, major mood swings, rapid weight gain, bloating, major anxiety, Im scared of everything right now & Im menstrating for the second time in two weeks. Are these symptoms of withdrawal or stress? Any idea whats going on with my body?
