Thanks for the responses, guys. I recall making the switch from Rexulti 1mg to Invega 3mg because I thought I needed to; I thought the Rexulti was giving me "mini" seizures, even at a relatively low dose. So I switched back to Invega 3mg because I thought it would be better for me. Well, it turns out I probably could have just stayed on the Rexulti because when I told my psych doc about the "mini seizures", he said to me, "I don't think you're having seizures." But he agreed to have me switch to Invega anyway.
The reason I reduced my escitalopram was because I thought I may have been on too much. Well, it turns out I wasn't. So I think if I keep my current regimen exactly the same, I will probably be fine. But the key word is "probably", so there is a chance I am still not on enough medication or on the right medication. I will have to discuss this with my psych doc.
