My husband got violently ill on the second day of treatment and was very ill all the way through. We had bouts with dehydration, weight loss, loss of function control and was even bed ridden for almost a month. It is not unusual to have the treatments affect one person right away and another barely at all and every stage in between.
Being overwhelmed is also a natural reaction. Most of us have definately been there.
Try to step back for a moment, take a deep breath and then move forward.
It was said to me many times, there is an end and things do get better. Hang onto that vision and you will make it through.
The ativan is common to help the anxiety that the treatments bring on. Tell him not to feel badly about how he feels physically at the moment, it is temporary.
Take one day at a time and mark your milestones and before you know it you will be past the hard part.
My best to you both,
Cindy
