depression
"Very strange anti-depressant with severe side-effects.

I've been on many different SSRIs over the years, finally settling on Sertraline which has served me well. It did however cause me to sleep too much so my GP suggested I try Mirtazapine. I'm only a few days in but I have to say this stuff is more like a powerful sleeping pill than an antidepressant. 

Far from solving my sleeping problem, this stuff has exacerbated it! It hits you really hard and sends you to sleep for 12  hours! The rest of the day I feel like a zombie; dizzy, exhausted and with strange visual disturbances (everything looks several shades darker and somewhat fuzzy).

I'll keep trying for a few weeks but I can't imagine it will be worth sticking with them."
