In my case it might, slightly, but the anxiolytic effect overrides it. I like the feeling of relaxation that comes, even though I know it will last only a short time-but I do know that it will happen for sure. It was the same with alcohol, but kava has little to no side effects (dry skin? dermo? tsh! big deal.). But logically it would seem that the heavier kavas would be somewhat of a depressant, again much like alcohol-depends on your unique depression profile my friend. I feel you and empathize with you fully.
Good vibes your way, and Peace!
