Hi there no - on rads - usually people are ok the first 3-4 weeks.. Rads is cumulative though so the last 2 and first few following treatment aren't fun but doable. I drove myself to all my treatments and was okay until literally the last two days of treatment but I was blessed, chemo made me somewhat nauseous but that's it. I looked like hell apparently but was okay - I am the exception most fall somewhere between brutal and okay - radiation makes it difficult to eat and drink and swallow there's a total lack of energy and your mouth is raw and food goes from tasting okay to metallic to literally no taste. And it's becomes painful to eat and swallow. Some drs recommend a feeding tube - this great to prevent weight loss but he must continue to swallow to prevent atrophy and permanent loss of his ability to swallow. Best of luck there's lots of advice here. Hugs!
