How to distinguish anxiety from akathisia?

Hello! Long time anxiety sufferer here. Was on Lexapro for 7 years then stopped for two.

I stopped smoking cannabis after being a heavy user for 20 years. Started Caplyta just before I quit and was on it for about 6 months. During the 6th month I noticed this insane inner restlessness. Like anxiety on steroids. Anxiety was building up until that point but like I said that last month it became unbearable. I would also wake up with what felt like adrenaline dumps at 3am and be unable to fall back asleep.

I’ve been off Caplyta for 3 months now. But I still feel this way to a degree. What’s hard for me is to distinguish it from anxiety. I ruminate like you wouldn’t believe and have anxiety about things I’ve always had anxiety about.

I’m able to relax and watch tv without moving my legs or anything but when I am working and under stress I notice I am moving my legs slightly.

Sleep has been a struggle since that last month of Caplyta and ever since. I was prescribed Quviviq for sleep with helps. Also the combo of passion flower, lemon balm and apigenin allow me to sleep as well. I still wake up in the middle of the night but am able to sleep on either or.

So is it Akathisia or just anxiety worsening? I haven’t spoken at length about this with my psychiatrist but I also don’t think she would think it’s akathisia but would attribute it to my anxiety that I came to her to treat. (My pcp prescribed the Caplyta before I saw my psych)
