Help! My October baby up every 3 hours at night!!!

Kelly
My son born 10/22 is up every 3 hours to nurse. I started solids with him and it has not helped. I also tried cutting back the amount I nurse him at night and it ALWAYS backfires, he ends up crying for a while and ends in me nursing him more. I am so tired and out of ideas. 
He does not do cry it out- it does not work with him. He will cry for hours, get so worked up and wakes up screaming after 20 mins. 
Any advice welcomed!!!
