I use Vitamin Shoppe's brand - 300mg at 80% Silymarin - 100 caps for $18 (that's 100 days worth). I've just gotten into the habit of taking one daily with my multivitamin at breakfast. If I'm really hungover, I might take two.
since taking NAC and milk thistle i never get hungover... i could be drinking the nastiest shit and i wake up feeling as if i never had drank the night before....before i would get hungover from just a couple of drinks
