I was just diagnosed with anxiety as it sometimes feels like a 50 pound weight is on my chest and I can’t breath. I hyperventilate and end up in the ER. 

My symptoms start to go away when the ambulance attendants arrive, and are completely gone in the hospital. All tests show healthy values.

I was prescribed 0.5g Ativan by one doctor, and 10mg Propranolol by another. I also started taking 225mg of L-Theanine in the morning.

Is it possible to mix these 3 Meds at the same time at these low dosages without known conflicting side effects?
