I've always had a hypersensitivity to any drug that could affect my CNS, meaning it usually made me too high
(SSRIs & Steroids included).
Long Story Short: Tried to go back on Paroxetine 6 months ago. Quit after a week...couldn't "come back down." Have had extremley low libido, lack of empathy, some confusion, difficulty thinking through problems, and have been devoid of many emotions like guilt, remorse, love, etc. Have been atypically charismatic.
