"i started this drug about two weeks ago. i was having a sudden intense depression. i had been taking wellbutrin 300 mg and paxil 20 mg. my psych suggested raising me up to 40 mg on paxil but i didn&#039;t like the sexual side effects. so he suggested switching to viibryd. he gave me a starter pack to use transition. i haven&#039;t had any of the mentioned side effects until the last 3 nights. my sleep has been very poor. hard to fall asleep and waking up during the night. even with a small dose of ativan on two of the nights. i am set to go up to 40 mg today but i might stay on 20 mg until i can talk with him on monday. overall my mood has been better (until this morning. not sleeping gets me fearful of another depressive episode)."
