How does a nursing mom catch up on her sleep if she is up with the baby (8 1/2monthsold) about 12 times?

My Son is still nursing but minimal in the daytime about 4 times a day and then 12 times during the night. I have tried feeding him more during the day but its a comfort thing so I dont know what to do. I am getting tired and need my sleep too and am running out of energy what can I do to a) either get him nursing less at night or b) catch up on sleep or c) take to give me energy and strength
