depression
"PHYSICALLY ADDICTIVE
It worked amazingly for what they were prescribed for (anxiety, depression, eating disorders) at first, but coming off has been awful and the doctors don't warn you about it. 
Do not try to come off cold turkey! 
Withdrawal made me feel like there was electrical current in the back of my brain, and the longer I went without it, the shorter the intervals between the brain zaps are. I still get it sometimes, but only if I forget to take it. I became really unfocused and disorientated for 2 weeks. I couldn't have conversations or work - I had no attention span and couldn't function.  I had to go back on them. 
They only go down to 20mg so I take halves, first every day, now every other. I've been trying to get off it for over 2 years"
