I've tried diazepam, lorazepam & alprazolam. I find lorazepam the most sudative and least recreational. The next would be diazepam, great for come downs (although be careful it can mess you up if taken like this). The best and most fun is defiantly alprazolam. Great feeling of well being, I used to like to do high doses and drink an energy drink, put me in a nice place where I wasn't drowsy but still had that nice buzz.
I'm currently withdrawing, cold turkey from alprazolam & diazepam. Just over two weeks now so through the worst of it. It was awful. My teeth hurt, my stomach ached, I felt confused, anxious, head aches and a heap of other stuff. Benzo's are good fun but tolerance and dependence can sneak up on you. Especially the Xanies. Man the more of those you take the more you need.
Try to keen it to once a week.
