Blue lotus works pretty well. You can buy it in dried flower form, tinctures, and resins. You can either smoke it, or apply to a glass of wine or vodka and enjoy.
Kava Kava from fiji or vanatu, not the cheap kona crap from hawaii. Try the resins/extracts 94% kavalactones. If you like the numb mouth that cocaine gives ya. It's a benzodiazepine effect like Klonopin/Clonazepam and Xanax. Hell, I was hooked hard on clonazepam after comin home from iraq till i tried kava...ill never take those fuckin pills again.
Both of these have reverse tolerances
