i poped my fuckign eardrum 3 weeks ago. went to the bottom of a pool for lifeguard training. my whole head fileld with water and it was so frustating when i was high becuase i couldnt hear. 2 weeks ago most of the water went out and, yes, my balance was totaly off. i think i got higher, just a little (maybe if was just me) but it was fun beign high and having bad balance. just do what your doctor says, and i doubt it from smoking weed.
