Linden tea and excercise! Cant emphasize the last one enough- youd be amazed how balanced it can keep you...also if your having like actual *trigger warning panic attacks I wouldn't advice you drink or smoke....yes not even weed
I think it's only worth it if you think you're going to be less exhausted at 3am than after work. Otherwise you might be draining your energy for useful, non-PT practice that could be done after work.
