No side effects. It just helped me get out of bed to use the bathroom or to take a bath with help. I had some sort of physical breakdown that put me in bed for a year and a half. Xanax also would lift my head out of the cloudy, depressed feeling that I would wake with every morning. Anti-depressents didn't work for me. Finding a doctor not afraid to prescribe Xanax has been difficult. I found one who increased my dose to 2-3mg a day. As my health improved, I gradually weaned off to only taking .25-.5mg. as needed.
