Thank you for your reply,
Nausea is definitely listed under the side effects of Propranolol, especially at such high doses. Anxiety is a very rare side effect but is also mentioned in the literature. I cannot imagine having to take medicine this often - how do you even remember? I prescribe Propranolol often for essential tremor but never in such high frequency dosing.
You can speak to your doctor about switching you to the long acting Propranolol which you only need to take once per day. The dose can equal to what you are taking now but it will make a huge difference in terms of your life-style and hopefully minimize side effects.
Also, there are other medications which can be tried for tremors, in case Propranolol is not doing a great job - for example, Clonazepam or Primidone.
I don't think Carb/Levo is responsible for your symptoms. It is usually a very well tolerated drug.
