Need hospital go bag suggestions

I may have to do a voluntary hospitalization tomorrow for an infection in the soft tissue of my left leg. I spent all day Monday getting iv antibiotics which did help some in getting my fever down from 103 to 100 tonight. I don’t want to just go up there & get admitted with nothing with me. I know I at least need my phone charger, toiletries & something to keep me busy but I can’t think of what else I may need. Any thoughts/suggestions?
