For me 300 is a good 1st plateau trip, especially with 2 or 3 beers just before I dose with DXM. 45 min to an hour later and I can barely walk, my pupils are huge and words are slurred my thought process is significantly skewed. Agreed there is no interest in sex. I rarely will get stimulant effects at this dose, but Im usually drinking so thats probably why. Height: 5'10" Weight: 165lbs
