When I was put on Prozac I had terrible akathisia. At that point it wasn't known SSRI's could cause it but I had a very brave doc at the time. He didn't know how to treat akathisia from SSRI's but for some reason I did (before the age of Internet and all...), so I suggested Inderal which actually helped!! Not at a 100 % rate but any relief was good.

Now akathisia usually passes with SSRI's but can stay with neuroleptics. That is a bit of concern since it means you can't stop the akathisia meds. I wouldn't worry about the Inderal, it is a benign med generally (unless you already have problems with low blood pressure or it causes you nightmares), I would actually worry more about the Cogentin. I know adding one more med feels bad, but since you already added the worst of them, don't worry about numbers... That is less important than tracking what the Cogentin does. Its effects can come even years after you started it.

If Haldol is what helps, I mean.. it's a harsh old med, but if it is the best for YOU, who can argue with that? We're not all textbook examples that can take the newest most fashionable (and most expensive) meds.

Don't worry about adding Inderal. Try it and see if it helps. Quality of life matters, numbers.. forget it. I always hated math anyway.
