What do I do if lately my Dad is starting to experience agitation and even panic attacks during the evening hours?

It seems that lately my Dad is starting to experience agitation and even panic attacks during the evening hours. It doesn't help that he insists on keeping his room at 80 degrees or more most of the time which exacerbates his breathing issues, but he keeps stating that he's "lonely". His facility has over 140 rooms in it, and it offers nightly evening activities which he refuses to attend. I think this is his way of trying to get ME to spend time with him in the evenings, but I've learned how to take care of myself and keep my visits to 3 a week (he sleeps during most of my visit anyway). He is currently taking Seroquel for agitation and anxiety, but he adamantly refuses to take it before 10 PM because he claims he doesn't want to go to bed earlier than that. In actuality, he's sleeping a lot more nowadays and usually has to be awakened for that late dose of medicine. Anyway, I was wondering if there were any suggestions to keep him calm until he agrees to take his anxiety pill.
