I'm sorry about your own advanced situation and the medication you are taking. I was diagnosed with locally advanced PC and went onto Zoladex and then had 37 RT fractions.
I understand about fatigue. It's something others cannot understand unless they have experienced it. Sleep does not always help it.
RT fatigue ceases after about 6 weeks.
Due to the age PC affects many patients many are already retired and do not have to worry about work.
But if you are working then life can be difficult.
I was very lucky in that my employers were supportive. I told all my colleagues personally when I was diagnosed and they were great.
I was signed off work after 7/9 weeks of RT for 2 months. And I needed that time off.
I went back to work on reduced hours ,initially 08.30 to 12.00 , then it increased over a period of 2 months until full time hours.
However I had a relapse of fatigue towards the end of those 2 months and the phased return was extended by 3 weeks.
During this time I spoke to a specialist nurse at PC as I just could not understand why I wasn't feeling better.
I was told that what I was going through was quite normal. And that it was the medication which is the main culprit.
Just do what you can and don't worry about what you cannot.
As my GP said to me " your health is the most important thing".
Trying to work and recover is tricky. You can feel guilty for being off but then terrible when you're back there.
It's taken me sometime to return to normal. And I found that surprising. But now I'm more or less there.
Re viagra, I posted a report called penile rehabilitation last week. You'll see that no one had spoken to me re ed and that it was only this forum that me think I needed to do something. Lyn is right re her posts.
We are here If you need us.
Good luck.
