I drank a bottle of regular pepsi during a tournament once.
It didn't help. I guess caffeine doesn't work for me.
Caffeine, etc. and Chess
Sort:
Hey, maybe chess engines or stimulants weren't in use. Maybe the player that beat you is currently better at chess than you. Maybe you're just having a bad day. 
Although I don't drink coffee, I have taken multimineral vitamins with an added ingredient of caffeine. Upon sitting down to play chess I was winning against my usual opponents to which I usually lose. The "culprit" was caffeine. I was very very alert and awake to spotting moves ahead and calculating variations. Go figure!
I think they should test the candidates and ban folk from using stimulants in especially world tournaments and chess championship games.
Irn Bru, Redbull, coffee (providing you can cope with irritability) may enhance your chess-results. :)
Overdose makes you fighting-fit & if your opponent Fritz or Houdini hasn't defragged their disk-drive in a while you have every chance of victory.
Coca-Cola used to be great until they changed the formula & USA has never succeeded in producing world-chess-champion since then...
>lost games
>engines or drugs increasing ability
seems legit, why don't you just accept defeat?

Caffeine can help you to not to lose any more games.
Go to Start bucks and purchase a grande with extra caffeine. When you return home, log onto chess.com
Before you start a game, pour the Starbucks coffee on the keyboard. Bingo you will never lose another game on the site.
Now for the local over the board games. Wash your chess set with some Starbuck coffe before the games. Watch those pieces just jump around trying to get into the games.
At local tournament if they are testing for Caffeine. Forget the cup they give you to fill. Just do it all over the chess set.
You won't lose any more games there either.
I guess I don't feel so bad anymore, having lost many chess games on chess.com for the simple reason that the guy on the other side of the computer could be using a chess engine or using a stimulant. Caffeine is a stimulant and has tremendous effect on enhancing brain performance and memory.Fortunately or unfortunately for me, for health reasons I'm not a subscriber or partaker of caffeine related products. I guess I will not go far in chess:) Do they test chess tournament players for caffeine prior to the matches? From the looks of things the great ones, chess champions love caffeine. What are your thoughts?
