Stomach upset and diarrhea!?

Hi first off please don't tell me to go to the doctor as I do seem to be getting better and I can't afford it right now. It started this tuesday around lunchtime I started feeling ill not puking just stomach gurgling and loose stool i ate lunch a little bit of candy and some cookies.....well that night it got worse i started getting muscle aches and felt feverish I took a tylenol and got sick a bit afterwards...the next day i had awful muscle aches vomiting and diarrhea...after that the next day i just had a mild headache no vomitting and some stomach cramps I kept down a soft pretzel.....and yesturday i felt somewhat better no headache or muscle aches just stomach gurgling and felt weak and the diarrhea....sooo my stupid self decided it was halloween and i wanted to have fun so i had two beers and some spicy food ugh well that night i suare i used the bathroom 20 times to the point to where it got very irritated down there :( i was up all night it was watery and still today I have used it 3 times already......IS the diarrhea sticking around because of my food and beer last night or is this something serious that I should worry about....I have taken some pepto and ate a yougrt this morning and a baked potato for lunch to stay on the safe side.....any thoughts or reuring would be appreciated thanks everyone
