Panic Disorde
"I took Paxil for 10 years.  Started on 20mg and had intense anxiety, confusion, panic. Doctor insisted it was all in my head.  Therapist told me to cut the dose in 1/2.  Felt somewhat better. Went up to 20mg after a few months and began to get brain zaps. A close friend told me I had lost my personality. Slept 10-14 hrs a night and frustrated my partner because of sleeping, no sex drive and no ability to feel sexual pleasure.  Effects of alcohol intensified-  passed out from 2 drinks or became over-emotional.  Tapered from 20mg to 0 slowly over the 10 yrs.  Each tiny decrease resulted in ~2wk period of increased anxiety. I think overall it numbed the panic but CBT therapy and getting older may have been more or similarly effective. "
