depression
"I lived in a world of gray with a circle of awareness as little as two feet. I was the quintessential invisible man. I tried all the  antidepressants for over 50 years.  Everything was totally useless and with horrible side effects to the extent that one wonders why anyone would prescribe it. The first thing that actually worked was Nardil which opened me to a world of light and color that I didn't know existed, but it had its problems and became ineffective after a time. 6 years ago my doctor finally gave up and gave me this. She started me on the low dose patch which didn't seem to do much  but the fog did lift . I seem to have few if any side effects. Emsam is worth trying."
