I decided to try Abilify again to see if it could improve my cognitive problems. I did try it before, but it had some nasty side effects for me: nausea, increased sweating, blurred vision, difficulty speaking... I didn't even try its antipsychotic properties since I discontinued it quickly.
Abilify is well known for its transient side effects which pass within two weeks, so I decided to give it another try. This time, I titrated it from 5mg. To avoid nausea, I took it with food, and indeed, it worked, bacause the pill didn't dissolve in my stomach. Nausea causes increased sweating, so I fixed this also.
I figured out that some antihistamines cause difficulty speaking, but Abilify has a very weak affinity for H1 receptor, so it shouldn't cause any problems, but it does cause difficulty speaking regardless. This is the main reason I discontinued it again.
I suspect that antipsychotic properties suck as well at 5mg, because after decreasing my previous antipsychotic (sulpiride), I felt some anxiety and psychosis returning. Well, it shouldn't happen, because I decreased the dose of sulpiride by only 33%. 5mg of Abilify should compensate for this, and I'm not willing to experiment with that when it obviously sucks.
Of course, it may work for someone else.
Now, I just want to try lurasidone (Latuda) once it is available in the Czech Republic. It's supposed to improve cognitive skills better than any other antipsychotic, and it has no affinity for H1 receptor, so no difficulty speaking for me (hopefully).
