Hi Ridgerunner
Sorry that you are here with us all, but this is a good place to hang out and get some questions answered ...
If you click on our "avatars" the pictures and/or our names you should be able to see a profile of the person responding.
I am not on Prostap. I am on HT though.
I am on triplet therapy which is a mix of HT and chemotherapy which will likely be followed by radiotherapy. So I get a double dose of HT (Zoladex and Darolutamide ) and fatigue is an issue. However the best response to this fatigue is to exercise! I walk as much as I can (10k steps a day) use an indoor bike, weights and resistance bands and have just joined the PureGym programme for those of us on HT (free membership for a year - look it up).
I also have recently taken up yoga.
OK I get tired but then head on out, get the legs moving and after a short while can get into a stride - albeit not at the pace I used to be able to do!
Use walking poles if able, make sure you drink 2 litres a day and I have found that a small foldable seat pad is useful.
Hope this helps your thinking - and do check your travel insurance policy....
