"i am 31 yo fem 5&#039;6, 115 lbs. prozac helps w/ anxiety but not insomnia. dr prescribed traz, start 50mg for few wks, move to 100mg if needed. last night was 1st 50mg dose. in 30min i was very relaxed &amp; slept really well. woke up w/ a bad head ache but it&#039;s gone now. i believe this rx will work &amp; will try 25mg for a few nights as body adjusts. for ambien users, beware that your body isn&#039;t only adjusting to new rx but also you are having withdrawals which can cause sickness, nightmares, sweat, nausea, etc. maybe slowly reduce ambien and then try traz. just a suggestion, everybody is different &amp; reacts differently. very good sleep, little s/e that should lessen over the next wk of use. i have tried natural remedies over several years w/ no help."
