anxiety
"About 4 years ago I started having early-morning awakening/insomnia/anxiety after excessive alcohol consumption the night before. Discovered that I could prevent this by taking diazepam my wife had lying around. When this ran out my GP prescribed lorazepam 0.5 mg. Gradually this lost effectiveness (tolerance) so I quit, also cut down on alcohol. A year ago I had a stressful situation and started 0.5 mg daily for a month, but was able to stop again with no side effects. However, my early-morning awakening/insomnia/anxiety had become chronic and independent of alcohol. A month ago I started 0.5 mg daily for 10 days, had a severe withdrawal, had to taper off. So, yes, like others wrote here: it works great, but not for chronic use."
