Still not back to normal

I still am not back to normal on the whole "feeling well" front. Friday night I tried to eat a little dinner and that didn't last, so then I tried saltines and water--nope didn't stay around long either. Saturday I woke up feeling poorly so Steve took Colton grocery shopping for their first "alone time" ever. I was a little unsure about the whole thing, but they made it back after several stops at three different grocery stores. I wasn't feeling too bad, so I loaded up Colton so that we could go to the barn. I went by Mom's to get her so she could help with him while we were at the barn. They had been talking about getting a new car and wanted to go over to the car dealership to see if his ginormous car seat would fit in the back seat, so I said I would go with them. We loaded up and went to Lake City. On the drive over, I felt ok. Once there, we switched the car seat and took the car for a test drive. We had to stop and get gas so I got a Ginger Ale hopping it would help with the nausea. I thought it was helping somewhat. After we took the car back, we stopped for lunch. I clearly wasn't hungry, so I got a table and waited with Colton. By the time they got to the table, I had to run to the bathroom and then go outside to get a little air. When I came back in, I felt as though I was going to pass out. We loaded up in the car and headed home. Once back, Colton went down for his nap and so did I. I slept a couple hours and then felt well enough to drive back home. I ate a biscuit for dinner and that stayed down. I slept pretty well that night and got up feeling not so queasy so we went to church and then to Sonny's for lunch. I ate a half a sandwich and that felt like a ton of bricks sitting on my stomach. I ate the other half for dinner and woke up this morning still feeling the same way. I have a headache and still feel sick to my stomach. I would go to the doctor, but I am not sure what he could do for me. If I am not better by Wednesday, I probably will go in though. We leave in a week on our cruise I sure as heck don't want to go on vacation feeling like this!!!
