dude i shattered my jaw last year playing football. sorry to hear about your ordeal....thats terrible man. I had surgery and got a huge plate put in but was not wired shut. I could not however chew for 6 weeks. I went from 220 to a frail 179 in that period of time. I drank about ten muscle milks a day and sucked on all the pudding and melted ice cream i could ever want and still lost weight. I must have consumed 3000 calories every day at least, but the weight still flew off. Ure stomache is gonna kill you eating liquid foods all the time btw. I dunno if your jaw needs surgery, but avoid taking the vicodine or oxycotton they give you at all costs. I took one vicodene on an empty stomache from not eating for three days and threw up for 2 days...and with a broken jaw it is the worst feeling ever.
As for things to eat....the best thing to do is blend spagettios. They actauly taste good, but watch the sodium. Yor gonna lose weight and tons of muscle no matter what bro. Sorry and Good luck.
