Hello Leonard, I'm sorry that you have need of this wonderful supportive site, but glad that you found us. I'm a bit confused by your treatment plan. You say that you will be getting two treatments on Fridays? Most Base of tongue patients are treated with 35 radiation sessions. One a day for 7 weeks.
Keep posting here with any questions you have. Someone will have experienced whatever is concerning you and will give advice. Christine will be along shortly with great advice on food and fluid intake . She knows what she is talking about.
Hello also to your Wife. Caregivers are amazing people who make this difficult journey bearable.
