I wish you luck.My hubby will never be back 100% either.With him we have had a weight problem with him putting it back on.
In 3 years he has only gained back 47 pds.He was at 250 before and the day I brought him home

he was at 146 this is a man 6'5...He has used weight gainer and all kinds of things.He looks great now.Not to skinny not to big.I miss him being a big man.When I say big I mean in a healthy way.His ring size was 13 now its a 11.
It takes a long time for some to make a come back.
If you can't do alot of working out his PT told use just watch your calorie intake.For a long time from being in a coma and on a feeding tube it was hard for him to go back to soild foods.But then again we had to start all over on everything.
Best of wishes for you.
