"take 150 mg xr plus 12.5 of the regular strength for anxiety and sleep. anything over 200 mg touches dopamine receptors therefore it ceases to be an ssri/sleep aid and is best for bipolar or schizophrenia. one pharmacologist wanted me to take much more. i did. i started hemorrhaging from my vagina until i cut all down to what i am taking now. works well as a sleep aid and anxiolytic."
