Good news, bad news; Bad news first, On anti nausea drugs, my experience was similar to David's. IMHO: Zofran, comprazine, promethazine and prochlorperazine were more trouble than they were worth and I ended up with three quarters of each bottle left over. I hope your experience is better.
Good news: At my worst in radiation I weighed 131 lbs and I weighed in at 177 lbs. I'm average height - 5' 11" and did not get any shorter That means percentage wise I lost one quarter of my body weight, yet my mask fit as snugly on the 40th radiation as it did on the first. Out of all the concerns my medical team raised over my weight loss - my mask not fitting tight enough never came up. I drank water constantly and never got dehyrdated but I did do like your husband only in reverse. In the last couple weeks I resorted to wearing a vest with fishing weights in the pocket and my heaviest Telson Danner SWAT boots, along with a blackberry and a biker wallet with massive chain and keys just to keep it near 140 so they wouldn't panic. I don't see many TV informercials about "fat faces" or new machines to "lose inches in those face cheeks". Most fat in on the waist, thighs, abdomen, buttocks, etc and would not affect a face mask. That said, maybe his RO needs some more practice on making masks if that is a constant issue with her patients. I would suggest getting a valid starting weight "do over" or else continue to wear the boots, etc.
