Withdrawal

 

Although research to date has been limited, there have been reports that prolonged use of high doses of GHB may lead to withdrawal symptoms after abrupt cessation of GHB use. Symptoms may include agitation/anxiety, insomnia, irregular heartbeat, muscle cramping and tremors. Withdrawal symptoms may be experienced from three to twelve days before subsiding.

Many heavy users report being able to taper off their use to zero by reducing their intake slowly over a two week period.
