My doctor has just put me on 10mg Propranolol to help with panic attacks and anxiety but I forgot to ask if it will effect my exercise (running, cycling, weight lifting, etc).
I'm just about to start a strict exercise regime and don't want to take the Propranolol if it's going to effect my performance.

I started by taking one 10mg tablet this morning and I've felt quite tired and slightly nauseous all day.
