The first one I had done, I left the place and went and pigged out... The second one however was not so nice. I had a reaction to something they gave me and woke up throwing up and was not able to eat anything until the next day and it took me days to recover form it. The proceedure I had done yesterday, I came home and ate a banana. They gave me something before the proceedure and afterwards for that. I will make sure I ask for that from now on~
