2 month old baby has colic, how can i get him to sleep?

My son is 2 months old and has colic. He will scream at top of his lungs when i try to put him down at night to sleep. His doctor has changed his formula to similac Expert care alimentum and told me that baby's usually grow out of it by three months old. I have tried playing music, swaddling, giving him a pacifier, warm bath before bed, i have also brought expensive evenflo bottles and to help reduce the amount of air he swallows when he eats, is there anything else I can do to help him?
