Has anyone ever felt stupid from Ability?

Hi all, I ve been on antipsychotics for three months and I m finally off them. For the most part it was Seroquel and then it was Ability. Now I m happy to say that I m off of it, but I m noticing that I ve felt extra lazy, low on energy, weaker in muscles, and worse of all I feel far less intelligent and knowledgeable than I used to be. As if my IQ has dropped. I ve also experienced some depression and trouble finding the right word. Has anybody else had this happen to them? I m worried mostly about my IQ because I m a college freshman (19) and the year s winding down. I used to have a 3.1 GPA and my grades were in the B+ range. Now they re in the C s and I m holding on by the skin of my teeth

P.S. I'd really appreciate a detailed response and anything I can do to get myself better.

Thanks for reading,

Jimmy
