alcohol is known to decrease your supply.
also, you can get brewer's yeast at any store that sells healthy stuff (whole foods, sprouts, CM, newflower, better grocers and health-food stores). It's pretty easily available. If you can't find it, ask someone for help...they may have the stuff organized differently than you'd expect.
