Have the stomach flu. What do I do about my meds?

So my son was sick on Thursday throwing up very bad as well as had very loose stools. He was fine as of yesterday morning but in the afternoon it struck me.
I was and still am very miserable. I haven't had anything to eat since yesterday afternoon except some jell-o and gingerale. I ended up in the hospital last night because I just couldn't get things under control, I kept vomiting and pooping and could not sleep to save my soul!
Hospital gave me Ondansetron for the nausea and of course fluids because I was severely dehydrated.
I plan on calling my GI on Monday but am not very sure about taking my Colazal after all of this, I don't want to end up throwing it up again as I did yesterday.
Have any of you gotten the flu with your UC? If so, what did you do about your meds?

The trick to surviving these random virus attacks: keep yourself hydrated. Sip a bit of water every 10 minutes-- then progress to a few sips of fruit juice after you hold the water down. I've found natural cranberry juice especially helpful in combatting nausea. When you can tolerate water & juice, try a small amount of broth. If you can keep the liquids down, take your Colazal. The colon needs every assist it can get, virus or no virus. There has been a really nasty norovirus going around NE U.S. over the past few months-- Eva Lou & I each got it & had an extraordinary amount of intestinal rumbling for days, in addition to some nausea + D that came out like a c-scope prep purge! Wonder if that's what you caught from your son ... It really was yucky. / Old Hat (30 yrs with left-sided UC; presently in remission taking brandname Colazal)
