The real hangover cure is two bags of saline IV, an oxygen tank, and a good meal. You put that trio in your body even sober and it will be the clearest high you've ever had. Most of the world spends their whole lives dehydrated. Our bodies are by far a majority of water. Do the math.
Are vitamins and any other supplement a substitute for good nutrition? Heck no. They're supplements, not substitutes. Unless you overdose on the fat-soluble (A,D,E,K) vites, and you can at a certain level since the body can't flush them out like water-soluble, they're not gonna hurt and can only help. The FDA doesn't regulate supplements so when you hear anecdotal reports that "such and such is a waste of money" it's only one person's ignorant mouth spewing rubbish and they may have also got a way underdosed supp. Some companies out there are feeding off the "magic pill" craze whenever a skewed study hits the papers and says a certain supp is better than sliced bread. As for people who talk about vitamins as if they're a fuel source, slap them like they was an armless dummy because there are only 3 energy substrates (protein, fat, carb) and thinking another substance like a vitamin can serve as a fuel source is similar to expecting your car to go a single mile off pure engine carbon cleaner. Square peg in a round hole.
There are a handful of vitamins, minerals, and other supps I take from time to time or almost all the time. If I run out or forget, no big deal. My focus is impeccable diet 6.5 days a week, and you always need that cheat meal to kickstart the metabolism if your intake was too low from eating clean the rest of the week. Study the crap out of diet for a year or two, get to the point where you can look at a plate and come within 50cals and 5g pro/fat/carb of correct estimate and you're stoked because you can basically plan out all meals and still enjoy what you're eating.
I eat a lot, but there's not a lot of things I eat, if you can understand that. Red meat is next to never for me these days. Salt is never added because it's too abundant as it is, and it's always watched. I do fish 1-2x a day 3-4 days a week. If I'm happily on and off the toilet quickly then I know I'm eating right because when you treat your body well habitually it lets you know the instant you do not. Hence, why I drink next to no alcohol.
Braddahs, please stay away from soy. It's in everything. Soy is a phytoestrogen (Plant estrogen) yet binds to estrogen receptors in the male body. We get all the E we need when it converts from T in our bodies via the aromatase enzyme and the older we get, the more feminized the male body becomes. Soy is pumped up like it's the effin fountain of youth simply because it's better and less carcinogenic on the female body than estradiol (natural E). But for us males, anything that acts as E in the body is no bueno. Our hormonal thermostat (negative feedback loop) is guided by E, not T, so the greater E our body senses the less of all hormones it will produce. In review, soy = less hard ons, more emo, more man tits.
PB&J, sage brah, I'm not saying I won't drink a half bottle of scotch ever again, but I've had enough hangovers where you literally think you're gonna die to know I've rocked out more than the average jetty bear. Not you sage brah, you're the bestest, raddest, baddest jetty bear there ever was in Deal.
