On holiday we would go to a cafe every morning to get freshly squeezed lemonade cos it was freaking amazing. One morning we were running late for an excursion and we missed our daily dosage, so we decided to go in the evening. Obviously the guy that had been working in the mornings for our breakfast run wouldn't be working in the evening, so we had a different guy making our beloved lemonade.

Now, being on those silly excursions you don't get to eat much so by evening time I was STARVING.

We order our drinks, panini's and a bit of cake, what ever else. As usual, the drinks come first. Doesn't look any different, so I take a sip and it is the most bitter thing ever, like literally sucking on a lemon. It was pure lemon juice - no sugar no anything added. Pure.Lemon.Juice.

The responsible people that I was with say they cant drink it because of its bitterness. I, though, rise to the challenge. I back that bad boy. 3 times in fact (mine and my 2 friends). They laugh as a I squirm with every sip. I finish the drinks, get a little chuckle from my uninterested audience and get on with my evening.

The next day though, I go to have breakfast and throw it back up straight away. Fast forward one week later, still can't hold anything down. Fast forward one week later, STILL can't hold anything down, go to the doctors (foreign doctors FYI), he looks inside me and says I've burnt the lining of my stomach. So I basically had an open wound inside me and was throwing food at it and it refused to cooperate till it healed.

TLDR: Challenged myself to drink an excessive amount of lemon juice on empty stomach. Burnt lining of stomach. Couldn't eat anything. Lost loads of weight. Sick bikini body after..Actually worked out kinda well.
