You need to fatten him up in a way that he does not realize what you are doing. He is probably more scared than you think because he is the only one that truly knows what he is feeling inside. This is the PERFECT time of year to make a nice stew!! Make the pieces of meat, potatoes and carrots so small that he really doesn't have to chew them. cook it all day in crock pot. I am no expert but he is probably having more difficulty than he wants to admit with eating. i know he's fighting you and hiding in the alcohol and cigarettes. Believe me i know it's hard to do but don't nag. Bribe him any way you can. think of him like your kids when you tried to make them eat there veggies. another good thing to make that is easy to swallow and cooks while your at work is stew. but NO hot peppers. green and red sweet ones and i cut up London broil real small along with chop meat and any and all kinds of beans (protein he needs that)!!
