Dude, I'm really sorry about what happend to you, did you just take too much and get too hot? Did a cold bath not work? What did they do to you at the hospital? Did you tell them what you really took?
I've read you should not increase from 200mg for at least 3 days because of its long half-life. And about the gym thing, bro I run everyday, like I do crazy shit. My ankles are in pain, I still tape them up and even throw a brace on - on top of the tape, and run. Ive changed my routine, took eca - ephedrine - caffeine - aspirin, etc... Now I'm jump roping and doing HIIT, hopefully that will work. And about the sweat part, theres not a single part of my body or clothing that isnt drenched every single time.
