Dizziness with UC flare/C-Diff

I have both UC and C-diff right now, and am probably having about 7-8 movements a day. Been kind of floundering with the Flagyl and now with the Vanco I'm seeing very small, small improvements of the c diff after 8 days of Vanco.

I'm having a lot of dizziness, lightheadedness and it's freaking me out, such an uncomfortable feeling and it's non-stop. I am not anemic at all anymore, I was just tested again yesterday.

Question is, when you're flaring/having diarrhea do you get dizziness? I'm drinking lots of water... is it dehydration? I thought if I kept my water intake up I wouldn't get dehydrated.. or do you think the dizziness is caused by inflammation? Or something totally different? My GI said it's probably ear related.. I don't think so.
I should add the dizziness started before medications.
Any imput would be great, thanks so much!

Thanks Bacon Girl.
How do you best replenish your electrolytes? I just started drinking a home-made oral replenishing therapy water of salt, sugar water tonight...is there a better way?
Why does the vanco deplete your electrolytes?

i'v heard gaterate isn't the best thing to have because of the sugar. I'm trying pedialyte. Do you think the dizziness is to do with the UC? Or something different? Has anyone had dizziness with UC?

magnesium in general can have a laxative effect
even magnesium sulphate (epsom salt)

let your doctor know those symptoms as they are very common with flaring and C. diff but could signal something serious
when was your potassium tested last?
taking oral pills for potassium may make not be a wise idea
I would recommend IV potassium when flaring if deficient
