"i switched from pristiq which was keeping me up at night. my initial dose was 50 mg. it was hell the first week: crying spells panick attacks but my doc promised it will improve. after i bumped it up to 100 mg the hell got worse; panick attacks&amp; anxiety were unbearable but i kept telling myself to stick with it. so, i did until the end of week 2 on higher dose when i was hospitalized with seizures due to serotonin syndrome. still taking ativan 1 mg every 5-6 hours for seizures. not a good experience."
