I personally found the Swaddle Me to not work very well. My son wiggled out of his. I would try a receiving blanket or they have Halo Sleep Sacks with swaddlers on them now. With the cold weather coming, it would be perfect if you just dress him in a long sleeve onesie or light sleeper.
I agree that he could just be hungry. We found co-sleeping to work well, but now my son is 5 1/2 months and still doesn't sleep well unless he is being held. :(
