Reintroducing one night feeding

My DS is 9 months old and we were bedsharing and nursing almost 10x per night and I was getting exhausted. So, last week, we tried to ST and wean night feedings. Well, he has one middle of the night waking that lasts 1.5 hours every night since the start ST. I'm thinking he's genuinely hungry now (I feel soooo guilty for withholding him the milk for 8 nights already). I feel like my supply has already dipped in 8 days. Do you ladies think it's possible to reintroduce one night feeding tonight? I really hope so.
