I was on 75 mg of Zoloft & I still wasn’t getting anything accomplished now I’m only on Strattera for ADHD which doesn’t work for me so I have two types of concentration difficulties which threw me for a loop for ten years I didn’t know I was depressed because it’s the same symptoms mostly as ADHD except my ADHD medication wouldn’t work. I didn’t know why then. Now I was takin 75 mg of Zoloft I thought I was ok but I increased it to 100 which I’ve been on before & I got depressed when I got used to it so I increased it to 125 mg & when I woke up at night & in the morning I was actually finally perfectly happy but then my meds overlapped dosage times & I went momentarily up to 150 & back to 125 but I got all sorts of dizzy really bad cerebral blood flow loss but it went away as I leveled out but so did the happiness. Now I’m on 150 mg so I don’t feel so bad while I’m waiting for it to “work” has anyone experienced this & does the happiness come back when it’s finally working I mean I was psyched not manic but fine. I want it back.
