[Harry Potter] For whatever reason, I'm a 20-year old muggle with a just-dead unicorn. I drink it's blood. What happens to me?

Who knows why. Maybe I stumbled across it just after it died. Maybe I freaked out and shot it. But for some demented reason I go and drink a pint of piping hot fresh unicorn blood. I'm an otherwise typical, healthy, run-of-the-mill 20-year old muggle. 

* I will never see this unicorn again afterward or have access to magic stuff again. Wizarding world never finds out about my act for the next twenty years at minimum, if ever.
* If I'm a guy, what does this mean for my life, physical health, and mental health, and possible future offspring?
* If I'm a lady, what does this mean for my life, physical health, and mental health, and possible future offspring?

Breaking up by biological gender in case it matters.

You probably feel pretty good. Those pimples on your back clear up and you wake up the next morning feeling great.

By the afternoon, you feel normal again. By the next morning, you get the shakes. Your skin crawls, your head is throbbing, and you **know** the only thing that will make you right is another taste of that magic rainbow drink, or *"U"* as you now think of it. You desperately search for an equestrian center nearby, but they only have *horses,* and that's not going to help you. No, your hemophagy can only be satisfied by the alabaster stallion's glittery blood.

In the throes of transcendent withdrawals, you either succumb or take your own life. You have no offspring, and if you did, they'd think you just really loved heroin.

Tl;dr- The actual cursed life is one of total addiction, not being sad you killed a pointy horse.
