yah nowons sounds like blackouts from booze lol, that happens to me at least once a week!
ive never had any thing like that happen while faced tho. its possible the brain ceases to "record" events adn happenings, even sensory memory, because of entirely too much internal activity. how large was the dose of amt? its psychoactive at very low doses, and a trip can result from as little as 35mg. ive never personally seen anyone do more than 50mg. I have met many ppl who has done up to 250mg, but id say thats pretty extreme. in any event, how large was the pill? a pill could be anything from 80mg (pretty small) to 200mg or more (pretty big) of material (not all necessarily psychoactive, of course). maybe you took a huge dose of amt and combined with lsd you were tripping so hard that hallucinations covered your visual field instead of sensory input from the eyes? or was it more like someone turned all the lights off?
