Actually, sleep and drug induced sleep is not necessarily best. Sleep needs to be proper sleep with good REM phases. The brain heals during REM sleep. Anti-anxiety meds (usually benzodiazepines) are rough on the brain. Avoid them if you can find other ways to reduce anxiety.

The standard is Quiet Rest. This means a low stimulation environment where the brain is not challenged with stress or cognitive tasks. Light activities like manual tasks in quiet atmospheres are best. The hands can not do tasks that over-burden the brain (except at a keyboard or smart phone). Knitting, painting, and other manual hobby like tasks provide low stress stimulation. You need to be active enough to support good blood flow through the brain.

For some, sleep may have been effective but it is not always the case.

My best to you.
