Propranolol and agitation

I take propranolol for essential tremor.  My Dr upped my dosage to 60 mg daily and I've been so agitated since the increase.  Has this affected anyone else this way?

Hi I took 80mg slow release for about 3 months and didn't feel agitated. I think the slow release ones are more likely to cause this as they wear off quicker.

Karen Im on 10mg ......do they work for you?

At first 10mg helped.  Especially with hand tremor, not much with head tremor.  However I now find I need to increase dose.  I didn't like how the long lasting propranolol made me feel.

I've had some agitation but not sure if it's the prozac or propranolol...I've noticed feeling weaker and heavy headed, some sickness in my stomach too...not sure which is causing which...pretty miserable.
