Hi Stormwine,
I don't have any tips for helping to calm your stomach or knowing what to eat; but I can sympathize with you. The morning of my final exam this past year before graduation; I couldn't eat my stomach was so wound up and I literally felt nauseous. I brought a cereal bar with me and when I got to school, and had calmed down a little more I was able to get that down before the test.
I too am taking my NCLEX tomorrow in the p.m. I'll see how I feel but I'll probably just try to make myself eat a little cereal in the a.m. and then maybe a yogurt before I leave. I usually drink coffee but I think I'm going to skip it tomorrow because sometime it makes me to jittterrryy and unable to focus.
Well, Best of LUCK TO YOU and all others who are taking the test tomorrow!! I don't know about you but I'm so sick of studying that I just feel that I'm as ready as I'm going to be and will be glad to get it over with. Best wishes again!
