I too went through hell & back with severe OCD. I tried almost all of the meds for it, and found that Zoloft was the only one that worked. I am currently taking 200mg a day. Have been for 10 yrs. I didn't notice any significant help until I got to 150mg. Once I felt the depression trying to creep back in, I went up to 200mg and have been there ever since. After years of NO sex drive (as a side effect) just recently I was also given Abilify, 2mgs. It worked like a charm. Much happier with life in general. If it's the creeping thoughts you are struggling with, I would ask about increasing the Zoloft, and maybe decrease the Abilify. I AM NOT a doctor, this is just my personal experience. I do wish you luck, it sounds like you're on the right track.
