Opinions¿

So I got off my anti-depressant not even a month ago and I've lost over 30+ pounds. It's affected not only my appetite but my sleep pattern as well. Any suggestions on what I should do? I know you all aren't quote on quote doctors, but I'd love an opinion from someone else. My mood is 10x better plus I didn't even feel a "change" with the meds being I was on them for so long.
