Ive been getting tattooed monthly for about 18 months and kava is really great to drink while getting tattooed. I drink it a little too much but getting through ribs or 8 hour sessions is pretty brutal so anything helps. I would double your water consumption if you can. Even try and get really hydrated a few days before. I always try and sleep better and relax a vouple days before a tattoo but fail miserably as I seem to always be doing some project or 10.
