Hi Lisa
I am very sorry for your ongoing troubles with Chewy.
Because Chewy vomited chunks in the morning before any food there is definitely a digestion issue. That’s the easy part, the hard part is figuring out exactly what is going on. I would like you to try a little food trial. Boneless, skinless turkey breast would be the best for this trial. Steam 4 oz of turkey breast until it is very well done then puree it in a blender or food processor. Don’t add ANYTHING except one ounce of water if needed to puree. Divide in half. Feed Chewy half of the puree for breakfast then wait 12 hours and feed the other half.
The pureed boneless, skinless turkey breast is about as low fat, low fiber and easily digestible as you can get. This will help to determine if it is a digestion issue related to fat, lack of enzymes or motility. Food that remains in the stomach overnight will ferment and can cause nausea and vomiting. I would try the puree first without any digestive enzymes for 2 days and if Chewy throws it up I would try again with digestive enzymes. I would buy a human grade product for protein digestion only, something like this:

Since the puree is only protein and moisture I would stay away from a full spectrum digestive enzyme at this point.
Chewy and you are in my thoughts and give the little guy a hug for me!!!
