No kidding. I've been malnourished before. There's a moment after taking vitamins and having a meal when it feels like the best drug ever. Better than dilaudid. Better than cocaine. Better than an orgasm. Apparently, according to my previous sexual partners and what I I've seen in pornos, I tend to have way more intense and longer lasting orgasms than most males. Still, the feeling of getting nutrients in my bloodstream after starving felt better than that...for about 20-30 mins! I was seriously just rubbing my skin and stretching my muscles, looking like I was in pure ecstasy. Imagine the peak of orgasm for 20-30 mins long. If that feeling could be turned into a drug, it would be the most addictive drug ever known.
I do intermittent fasting (apparently, wasn't aware of the concept until a friend of mine was describing it as there new diet plan and I was like "Damn, I've been doing that for years") and usually feel like shit after I eat. Not sure they're related though it might be that I just have a shitty digestive system.
