Propranolol seems to be working for the restlessness. Now I'm not sure if my restlessness is due to anxiety or akathisia/RLS. I kinda wish I could have tried cogentin. At least if I tried that, I would know for sure if it was akathisia or not (i.e., the rexulti giving me problems) since I can imagine cogentin would not work on anxiety-induced restlessness.

As an aside, I think propranolol's 3-6 hours of half life is way too short. I have a full-time job with meetings always popping up at the last minute, so I can't always take propranolol during the day. I may literally have meetings all day with no break. That's why I have an extended release Ritalin capsule that I take as opposed to taking two Ritalin tablets during work hours.
