The following is a few extracts of information I've posted on forums while experimenting with this substance. *Initial report upon receiving the substance: Just smoked 15mg, very odd effects..

Reset
Falls after you stop, at a rate that varies from person to person. If you've been using regularly, cut down gradually with medical help rather than stopping suddenly.
No tolerance chart. Our decay curves for these drugs were estimates, and a curve can make tolerance look longer-lasting than it is, which is the dangerous direction.
How fast tolerance to these drugs fades after a break has not been measured well enough to draw, so don't count on a dose you used to take still being safe: after time off, start with a much smaller amount and don't use alone. Mixing sedatives with each other, with alcohol or with opioids sharply raises the risk of a fatal overdose. If you've been using regularly, don't stop suddenly: withdrawal from benzodiazepines, alcohol or GHB/GBL can cause seizures or delirium, so get medical help to cut down gradually.

Effects
Aggregated from 3 single-substance Erowid experience reports
Each bar shows the share of analyzed reports whose text mentions that effect — a mention is not always a first-hand experience (fear of an effect or something witnessed can count). Mentions saying the effect did not happen are left out; that check reads keywords, so it can miss some. The shaded band on a bar, and the small range after its number, is the 95% interval: where the share could plausibly be with other reports of the same kind. Fewer reports, wider band. Tap or hover any number for details. The second value is the Bluelight extractor's per-effect confidence; a dash means the row is Erowid-derived, which has no confidence measurement.
Too few reports for bars: these effects come from 3 single-substance Erowid reports, and a bar is drawn only from 20 reports or more. With fewer, a percentage cannot tell a common effect from a rare one. Counts are shown instead. Why 20?

Erowid 2 reports 2 cautionary visit
I've always wanted to try methaqualone. In Canada its only Schedule 3, so can still be RXed under the brand name, Sopor , but is often overlooked in the name of the allegedly less dangerous benzodiazepines.
Bluelight 3 threads 1 neutral 2 cautionary visit
Hey all, So i recently managed to get my grubby hands on some mmq. having drooled over qualuude reports in the past i was quite excited. Unfortunately, my scales were at a friends house and I was too keen to wait.
No pot in the house, dealer busted the day before, anxiety setting in. I'd had some Pentobarbital the night before to get to sleep but I was weary about taking that so soon. I dont want to rely on another thing like i rely on pot to go to sleep.
I recently aquired some methylmethaqualone from a trusted source and took it 3 nights in a row. 1st day: 60mg 60mg +30minutes Within 30 minutes of first dose felt happy and smiley, not too intense could have been attributed to placebo.
