FTM help!

My son is 10 days old and I am exclusively breastfeeding. It has been going ok. During the day he's pretty much eating every 2-3 hours and napping in between, but at night he wants to eat almost every hour! I had finally come to terms with the fact that I probably won't sleep at night for a while,but now he's starting to fall asleep at the breast almost every time I try to feed him. He also gets super gassy so his feedings take an hour or more.
