I used to suffer extreme man colds as well, but losing the weight and quitting smoking/vaping did absolute wonders. Now when I get a cold I just rotate Acetamenophen and a low dose of Ibuprofen if I really need it, and take Echenacia 3x daily as though it's an antibiotic, despite wise internet sages needing to remind me every time that it's a placebo effect or their fucking heads will explode. Fortunately for me it's a placebo effect that yields excellent results, unlike the copious amounts of other alternatives I've entertained that didn't do shit for me.
