Hello i'm taking sertraline for 6 weeks now. I've increased gradually, up to 150 mg since 3 weeks. I was on citalopram since 15 years but it didn't seems to work anymore so I was putted on Zoloft for severe depression and anxiety. I'm starting to lose faith in sertraline since I have no positive effects (maybe the only one is appetite is back) for 6 complete weeks. Can it take longer ? I've red maybe 7-8 weeks ? Should I wait 1 to 2 other weeks before asking for an increase or another pill ?
