My husband has finished his 4th week of radiop/chemo but hasn't been able to keep anything down for about the last 5days. We spent the day at the hosp getting rehydrated with IV's. He's tried compazine/zofran/and suppositories for the vomiting. When he puts anything but gatorade in his peg tube he vomits. He's down 30 lbs. with over 3 weeks to go. Any suggestions appreciated.
