I am adhd and am prescribed to Ritalin (Methylin, or so says the pill bottle). I know that when I take too many I get really really calm. I took too many at a DECA conference and laid in bed for 2 hours while people were running around in my room, I just could not move. Another time I took 3 pills with a can of beer than smoked 3 blunts and I will never forget that night. I went to my friends party after doing this and drank a beer or two and after that I was couch locked for a few hours.
That is what happens to me but my friends often ask me what will happen if they take them alone or before or after smoking weed? The pills, like the title says are 20mg each, can they in any way hurt them or just fuck them up and to what extent?
