So I haven't been feeling well I have been having stomach cramps and n* since last night around 5:30. I've also felt pretty tired for the past 2 days. I don't really feel like eating although I can tell that I'm hungry. I'll probably have eggs and applesauce once I'm up to it.
Last night, I couldn't fall asleep. I was very gassy and felt like I had a fever, and I finally got up around 3 am and had d* one time. I took pepto bismol and drank some water after that, then finally fell asleep.
I woke up feeling okay around 8, but now it's 10:30. I'm feeling kind of n* again.

Yesterday the things I ate were eggs (omelet with feta), watermelon, banana, a luna bar, a veggie sandwich from a meeting at work (with provolone, mustard, tomato, lettuce, carrots on wheat), then for dinner I had a salad (with feta, croutons, honey mustard dressing & craisins) and I had 1 beer after.
The only thing that worries me is the sandwich from work - it was served in a sanitary way, but it always worries me to eat things that I didn't personally prepare.
I'm also nervous because one of my coworkers is sick. The last time he was at work was Tuesday, then he felt sick that night and didn't work Wed - Friday. He has cold symptoms plus v*ing! I didn't come into contact with him but I worked in the same place.

I know fp* or a sv* usually hit super quickly, but I'm confused about why I have these symptoms.

I need to feel better because I'm having people over tonight for my roommate's birthday! What is wrong with me and what should I do?
