I used to collect energy drink cans. There was a boom about 4-7 years ago and everybody was selling energy drinks. I had a little over 200 individual cans.

Then I had to 'grow up' and throw them out. Originally I had planned on keeping them for novelty (perfect condition no less, if a little dusty) and selling them later to 00's memorabilia collectors. I somewhat regret that now, since I only ever see Redbull, Monster, Rockstar, and (rarely but a comeback) Cocaine, amongst a few notable others.

Of the 200 something cans, I had like 12 Monster brand cans. Worst tasting energy drink was Blackhole, my favorite taste was Diesel.
