I concur with Aloha and [...],
Sleep restriction has about a ZERO percent chance of working under Benzo-induced insomnia.
It can work to a certain degree if your insomnia isn't caused by coming off of Benzos, but there are NO Shortcuts or ways to "trick" your GABA receptors into healing and/or regrowing...only TIME can do that...
Throw all sleep hygiene out the window during Benzo-induced insomnia....none of it works...it can't because none of it can repair the Temporary damage to your GABA receptors and Central Nervous System! And everyone has GABA receptors throughout their body with the highest concentration in the brain and GI Tract.
