Last night SWIM decided to take his 1st trip in awhile. So he had his lab rat ingest 450mg the highest dose the rat has ever ingested (his rat is a light weight). my rat's night went pretty normal untill he had the rat lay in bed, while listening to radiohead with the sheets over his head my vision almost went blank its hard to explain. I say it was almost like a sheet of multi colored plastic was pulled over his eyes. His vision was almost grainy he says it was beautiful. So I was wondering if that is normal at higher dose levels. SWIM at one point thought his lab rat had zero tolerence to DXM but finally realized thats just what the drug does and is begining to increase dosage.
