"a week ago i would have rated it less. today (a month and 5 days after starting it) it&#039;s a 10. i started on 50 mg sertraline, which i&#039;ve been trying to tolerate for the past 4 weeks. nervous and hard to concentrate. for the past few nights i&#039;ve been taking 25 mg (splitting the pills in half) before bed with 1.5 mg (half pill) of melatonin. yesterday i decided to stop taking my ginkgo biloba supplement because of info i read about it with zoloft. that night, before bed, i took the 25 mg, but waited till it woke me up to take the melatonin. today i feel great! hopefully, after doing the same thing tonight i will feel the same way tomorrow."
