So sorry to hear your bun is poorly. 
I hope he has a speedy recovery. I’m not the most experienced bunny owner here, but all I can say is syringe feeding is what probably helped to save one of my buns from suffering more from stasis. It’s not pleasant for them (or you!), but it’s definitely the lesser of two evils. My bun wasn’t eating or drinking anything at all from the stasis, so I could handle her having to be uncomfortable from syringe feeding vs. the more serious effects of GI stasis.
