Is the GBL for sleep or fun. I was doint it all the time, enjoying it, thought is was the greatest drug in the world, then 2 of my friends passed the f**k out and stopped breathing, had to call 911, ambulance, Intensive care all the works, Scariest day of my life. Be careful with that stuff. Alittle goes a long way, my advice dont ever share it with people. I mean if something go wrong can u live with a buddy dying, or ur girlfriend.
