Well, I found out through your other posts and the message you sent me that it was NO2 and No-Xplode mixture?
What exactly did your doctor say? Go ask him/her if you can do any exercises, even light at the moment. I'm anticipating they would say it isn't safe for you for the moment, so if they say no, ask them why exactly, what are the consequences and how long will it be before you can start working out.
I have little clue with what you meant by "anxiety". Are you just randomly jittery or what? When are you getting these anxiety attacks.
Obviously, for the moment, stay off the supplements, and stay off anything that can alter your heart rate such as energy drinks, coffee, etc. You should give your body the time to start relying on itself for higher stress levels of work instead of caffeinated products and the like.
