Hi Hip--Because allergens (and toxins and viruses, and just about everything else) all screw up my sleep, I'm always looking for remedies for insomnia. GHB sounds really strong, and some of the side effects are a bit intense--nausea and vomiting, loss of muscle control, depressed respiration, hallucinations, agitation. It's known for being the "date rape drug." If taken in large quantities, it causes total unconsciousness. And also, from what I've read, it can be addictive, and can cause some extreme withdrawal symptoms, which put "extreme stress on the heart and circulatory system." On the positive side, "The natural function of GHB in the body might be to slow down brain activity during sleep. Gamma hydroxybutyrate affects several nerve pathways in the brain, including activating the body's pain-killing (opioid) system and raising levels of growth hormone. All that does sound appealing. When you took it, did you feel any of the negative side effects, and how did you feel when you stopped? Did you have withdrawal symptoms? Did you have long term negative effects--like issues with mood and memory? Any additional input about it would be helpful.
