Propranolol
"I was diagnosed with hypothyroidsm and extremely low levels of vitamin b12 which were wreaking all kinds of havoc in my body, so my doctor prescribed me Propranolol for high blood pressure and rapid pulse/palpitations, and it did really work for both problems, helped a little with my anxiety too, but I quit it after ten weeks because I was so drowsy all day long, I also started breaking out pretty bad in the face, scalp and hairline, not sure if it's related to Propral, but at least the fatigue and general "depressive mood" subsided instantly when I stopped taking it."
