I think getting rid of the Paci might help, but if you think he is tired from daycare, then I'm guessing it is the overtired part that is making the waking worse...I had that problem with my ds#1 who didn't nap properly at daycare, we went through a few months where we pretty much got him home & put him to bed...I felt like I never saw my son on those days, but it slowly improved... don't know what other advice to give.
