there's some i don't really like even though there's a few to pick from. There's some popular ones liks NOS, monster, red bull, amp, rockstar, annnnnd some minor ones in random stores. Right now I like red rain the best~ it's only in one food city in town XD it's also pretty cheap for an energy drink, but still costs more than soda.
The best thing to do is drink several glasses of water each day~ the more the better :P but it can't be any water, since there's stuff in water depending on where you are. you can get filters installed or containers that have filters. Well water is the best way to go.
I've read a book about how important water is~ :P
annnd i'd never get into things like alcohol, smoking etc. It's best not to get a bad habit if you plan on having kids~ :P
