I cant be sure, but my heart beat seems to be speeding up and slowing down, thumping hard and light. I have been insufflating ritalin. Any advice? Is this serious?
Sounds like an Arhythmia (abnormal heart beat), this isn't a good thing. Are you prescribed ritalin? If so talk to your doc about it, they'll most likely take you off it. If you aren't prescribed it then stop doing it since you don't need it and it's causing complications.
