Is it a big deal to skip a dose when sick?

Im coming off a 5 day nasty stomach bug, which left me so dehydrated I ended up in the ER Friday (POTS and dehydration = very bad). I've just started eating normally. My regular shot should have been yesterday.

I dont want to push my body too much, need to make sure I'm still easily able to keep my fluids up and get nutrients into my body, and I just want to have a few days without nausea (always have that side effect for a couple days after a dose). I'm on 5mg.

Is it a big deal to just take my next dose on my regular day, meaning I skip this week's? Or should I take it tomorrow and worry about changing my day back later?
