Im at a crossroad and learned a lesson about this... its for employment... the bottle is 25 oz, and I cant finish it. I need to fill it back up AND drink all that too... If I drink anymore ill throw it all up and then its hopeless... I hope Niacin diet + working out + half a bottle of herbal mask + no weed since the 25th + water will equal results. Oh! Anyone ever have a follow up drug test right after? My employer told me it was a one and done, but I know how that works...
