chemo has immediate effects for many
radiation takes (usually) 2-3 weeks to kick you in the hiney
each person is different though and the more built up you are
prior to beginning treatments and the more well nourished and
hydrated you remain the better you will do thru it.

the peg tube is a huge blessing and not hard to use. it is a bit painful at first (figure about a week) but it gets better ... watch for redness and increased pain in case it gets infected as he would want to get that treated if it happens but most go thru it just fine and are thankful to have it for backup when the mouth gets too sore to eat normally

most report feeling over the initial "hump" about 6-8 weeks post treatments. this varies so much by each person though and how big of a hump there is to conquer also varies so one has to remain positive, and be proactive when you see problems beginning to arise. there is usually help for all problems you may encounter so speak with the doctors and nurses as you go and he needs something - make sure they hear you and respond with help ... if they do not - speak to someone else or speak again and again until they listen.. there is no need to suffer when there is help available.

i wish you and hubby all the best. by mid feb you should be looking BACK on it all and being glad it is all behind you.
