Success !!!!!

I was able to get two 1ml syringes of Miralax and Laxatone down him. He thought he was going to get treats and let his guard down

Later on today will try to do the gabapentin too but may be pushing my luck.
He didn't seem to mind the mixture of laxatone and miralax, which really surprised me (necessity is the mother of invention) but the gabapentin is bitter tasting. Perhaps I'll have tuna fish for lunch today and mix the juice with the gabapentin in the syringe and see if that works. Then if that works, I'll just plan on having canned tunafish on the days he gets the gabapentin. I'll switch from water packed tuna to oil packed tuna, I like that taste better anyway, lol.
It helps to talk this out here. I appreciate everyone's input and support. Will keep you posted
