5 Hour energy drink sucks for me.
I had not even half of one once and got such a bad headache that I passed out and started having nightmares.
But I think my favorite would be the original Monster.

Ironically, I once got a headache and passed out when I had too much caffeine.
It happened while I was at an internet cafe when I was younger. The staff kept selling me the drinks (because they got a lot of other customers) and didn't notice.

I didn't know I had been drinking energy drinks (as they weren't labelled). I forgot which drink I had, but I had drank more than 3 in less than a 4 hour period.
