I don't. I have a vitamin sometimes when I remember, but I don't drink booze, tea, or coffee, smoke, take antidepressants, focus drugs, anything. I also don't play with essential oils, homeopathy, crystals, or other placebos. Heck, I don't even take painkillers or headache medicine unless I've got stitches. So, while I would agree that most probably do, you can't say 'everyone'.
