why isnt he sleeping EVER!

ok so as you may know Dominick has NOT slept through the night in about 2 weeks at first we thought it was because of his 2 teeth coming in at the same time, but now im starting to think otherwise. He hasnt been going to bed ontime and has been waking up 3 to 4 times a night. like last night he refused to go to bed until midnight and woke up at 2:30, 4:00 and again at 6:00. now obviously i wont give him nyquil but is it wrong to want to just to get more than 4 hours sleep in one night. I am beginning to not be able to function during the day and having to work full time and this its just not getting any easier. If there is any suggestions (CORINNE!) please help me! Im still a rokkie at this and basically have no clue what to do! Im prying that it is just his teeth but something is telling me that he is like me when i was a baby and had my days and nights mixed up.
