Hello J.,
I am a mother of two boys ages 3 and 13 months. One thing I have noticed nobody has mentioned is, have you tried the bedtime lotion made by johnson and johnson. But some on his body after his bath and also put it on his shirt so that once it wears off of his body he will still inhale it from his short. My oldest was the same way, we would feed him some rice or oatmeal cereal with applesauce mixed in while he was in the tub, then lotioned him up and it really helped. It could also be that he is teething. I have learned with my 13 month old that the teething tablets work well at times but the orajel does not. Take a q-tip and dip it in vanilla extract and lightly rub it on his gums and it will sooth the pain that he has by numbing them. My oldest started teething at 4 months but his first tooth did not come in until he was almost 8 months old.
Another thing that helped was I got one of the toys that attaches to the side of the crib that he can push the button and it has a light and plays music. It is made by fisher price and he would lay in bed and play for awhile and then lay back down and go back to sleep.
Good Luck
