For about a year and a half I have been taking GBL as a sleep aid and as a replacement for alcohol. A good friend of mine sells the stuff for a fairly decent price. Recently I have found sites that sell the stuff for much cheaper though. I have also researched the synthesis of GHB which can be made simply by a combination of GBL and NaOH. I understand that GBL converts into GHB when ingested and I'm sure that GHB stays as GHB when ingested also. My question is if GBL converts into GHB what benefit does adding the NaOH to GBL have? Does GHB offer any more benefits than GBL? What are they?
