Update if anyone is interested. Woke up Wednesday, my stomach felt alot better but felt all wonky in the head (dizzy and spacey) and had the chills, my teeth were chattering, slight fever around 99.4, I stayed home and slept most of the day. Today I woke up and feel fine, no fever. Took the day off just to be sure. So far so good. Been taking a few doses of Sambucol since yesterday, forgot I had it, tastes good.
Edit: Took a nap today, woke up feeling a bit wonky. I guess it takes awhile to totally recover from a virus.
