ok so my 30 days are almost up! I am still drinking my 2-3 litres of water a day, and I have been taking my niacin, every day, and also I have been taking metamucil every day three times a day. I am not sure at what rate the niacin helps kick out the toxins but I have been on them for almost a week now. Can any1 tell me if it possible for me to be thc free? And no somking for 60 days now! I am hoping like hell my levels have dropped low enough to pass the next test!!
