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.

Gender: Male Age:27 [Set/Setting: see below] Psychonautic Experience Level: Advanced Etaqualone is an insidious creature.

Disclaimer: This is little to no info on the half life, metabolism, safety of smoking, or bioavailability of this substance. I don't advise you to consume it, but if you do, please be careful, and don't be swayed by people saying 'I took 3x that much and nothing happened'. That can easily leads to mistakes.
Had lots of experience with all kinds of downers. I took 1mg etizolam and 100mg tramadol the night before this, besides that only pot smoked all week. 10:50 swallow approx 500-mg its odd dumping a big pile of powder without some anxiety as the powders I handle are usually active in amounts 100's of times smaller then t...
