I've been using GBL regularly for sleeping, 3.5ml and then on the 4 hour awaking 2.5ml for maybe 8 months. It helped me a lot to reduce my nightly alcohol consumption, which was my previous hypnotic.
According to a study with Xyrem such use will not lead to significant withdrawal symptoms.
Recently my chronic depression exacerbated, and I started to use GBL occasionally during the day, in doses of 1.5 - 2ml.
Finally, three days ago some disaster strike me, and since I'm using GBL quite frequently in the same dosage range. It helps me quite a bit.
My concern is that I absolutely want to avoid real hard physical dependance, the sort where I get serious withdrawal symptoms. Btw, I'm sitting on 12.5 liters of GBL, and it's legal here. So there's no immediate shortage of supply.
My question is: how long did you take how much GBL or GHB and what was your experience on withdrawal?
I've found two case reports on Pubmed:
A patient taking about 181 g/day GHB for 4 months, for its euphoric and anxiolytic effects (Addolorato et al, 1999). On discontinuation of GHB, the patient showed a withdrawal syndrome consisting of high anxiety levels, tremor, sweating, tachycardia and nausea. Complete disappearance of drug withdrawal symptoms was achieved within 2 hours in the first day of treatment with diazepam 20 mg orally administered...
A 43-year-old male reported using GHB for 2.5 years. The effects of use were reported as feelings of relaxation, inner well-being, increased appetite and short, restful periods of sleep. Starting doses of GHB were difficult to quantify as it is generally taken in liquid form. The patient said his dose was originally 15 ml irregularly, but had increased to 30 ml every 3 hours by the beginning of 1999. The patient reported withdrawal experiences such as feelings of panic, terror and anxiety, often with a tremor. Other autonomic features included diarrhoea.
In other cases pentobarbital had to be used to control withdrawal signs:
The amounts of GHB consumed above sound huge to me. What's your story of GBL/GHB use and withdrawals?
