I have been using Now brand bottled kava (250mg 30% kavalactones). It definatly relaxes and frees the mind of stress. I took 4 of them right before bed and had a very vivid, sexy dream , a level of vividness I've never expierenced before. I only take the kava once a week. The local natural foods store also has liquid extract, if that's anymore potent I might try that. I am almost certain Kava's effect on dreams is entirely placebo, but it does relax and clear the mind for sleep.
