Hi Dan

Provided there are no complications, I don't see why you can't do both weddings. These events may even provide sufficient motivation to keep you really looking after yourself during treatment. However Christine's point about your immune system is a good one, you really need to look out for your health around crowds of people. Why don't you ask your doctor for their opinion? I know they will sit on the fence about whether or not you will be well enough to go, but I am sure they will give you an informed opinion about your risk of infection around people.

Chemo will knock you around severely for the second week of the cycle but you will feel much better (almost normal according to Alex) on week three just before the next round of chemo.

May I suggest you organise to have a hotel room or a quiet place close by all the events which you can retreat to for a bit of a nap or just a half hour rest if need be. You can have a Plan B person to step in should it turn out that you are unwell, but I feel that the prospect of being the "proud father" will keep you motivated through the worst of your treatment to keep yourself hydrated and fed which in turn will help your recovery.

My Alex, was mostly upright through all of his treatment which ended on the last day of August 2010. 6 weeks after completion of treatment his mother died and he flew to New Zealand (about 3 hours) managed the appalling delays through customs and stayed upright through all of the angst and grief that goes with funerals.

You have rightly deduced that the wedding most at risk is the one that falls at week 8 or 9 of treatment, as this is likely to be the time you are feeling your worst. I believe you will at least be able to walk your daughter down the aisle (provided you keep your nutrition and hydration up which will help with recovery) and it would be great if you could take a break between ceremony and reception to recharge.

Like everyone else, Alex was weak and easily fatigued but looking back, I think we could have done what you are contemplating with the safety net of somewhere to go for a rest between activities.

You don't mention whether or not you will be flying down the day before the events start but assume you will be doing this so you have time to rest after the flight?
