I was recently prescribed
Adderall IR 10mgs, and the weird thing is, I can breathe so much better. I notice this because after it wears off, I can tell that my breathing has gone back to being a bit difficult. I don't like taking the Adderall all the time, but it seems to have this excellent side effect.
When I research this on Google, the majority of articles are about Adderall and shallow breathing, but I have the exact opposite effect--I can breathe better, deeper and more efficiently.
