Summary
Ethylbromazolam is structurally similar to bromazolam with an ethyl instead of methyl group on the triazole ring. User reports suggest approximately half the potency of bromazolam, with reportedly less sedation and amnesia than its parent compound. Estimated equivalence: 4 mg ethylbromazolam produces effects similar to 10 mg diazepam.

Strong anxiolysis with strong cognitive impairment, moderate euphoria, mild sedation
Tolerance
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.
