Sickness help? :( please help :( ?

I've been sick since tuesday evening, I was sick 4 times that evening, and then on Wednesday morning at 10am I was sick a couple of times. However throughout the day I felt better so after 6/7 hours I had a slice of toast. I felt fine, but then I woke up at 5am this morning and I was sick 3 more times. I still feel a bit sick now, and I really want this to go away for Saturday because I'm going on holiday :( please help! What should I do? Eat? Drink? HELP ME :(
