I'm currently on a beta blocker (Inderal[Propranolol Hydrochloride]) for headaches due to high blood pressure. I've only been taking them a few days but I get the feeling that they sometimes make me feel "washed out" during my normal commute (after 15-20 mins). Is it possible the medication is messing about with my blood sugar levels? I noticed that they are not recommended for diabetics (I am not one). I was thinking of adding some glucose to my normal riding drink to help out.
I must admit that the medication has not had any other discernible affect.
Any suggestions would be most be welcome.
