Feeding time and vomiting

My cat was on Cerenia for several weeks and now off of it to see how he does. Yesterday I fed him 1.5 nuggets of Primal frozen at 7am and noon, then 1/4 can of NVI rabbit (5.5oz can) at 5pm and again at 9pm. He's getting about 250 kcal a day. Then, he started bugging me up around 1:30am, and vomited around 2am with bile. He usually vomits when he's hungry. I wonder what I should do about it. Should I feed him during the night (with timed feeder?), or is NVI rabbit too lean? I did add some prozyme to the canned food, though, and maybe it made him hungry so soon? (I also added some fish oil and Vetri science derma strength chew). 

I feed my cats only wet food. I add water to food. 

My cats vomit when their food dishes are placed on the floor. I was advised to buy them a raised feeder like the little one shown below. It works really well and they don't throw up their food now.

If you think its the rabbit. Try feeding something else. But if its bile.. Can you feed him later then 9 pm? My cats could not go that long. I feed the last feeding at 11pm. Then am at 7.

Last night I fed him around midnight (NVI rabbit again) and he slept through the night until 7:30am. But I resumed cerenia also. I fed him a little more during the day yesterday, so, maybe he wasn't getting enough food...
