Hi Negita, I'm at a similar stage as yourself. Diagnosed 14 months ago , 28 shots on the Linac, 5 shots of hormone. I suffered a major reaction to the treatment at around the 22 Linac shots which hospitalised me and since finishing the full course have been on a steady course of regaining strength and health. I would not say I have any issues that are not manageable or restricting my lifestyle however there have been and are side effects as follows:
Hormone treatment hot flushes are crazy in a hot climate and when they occur it feels like my head is boiling. I would not say it has altered my moods and certainly not led to depression. Decreased libido but not completely destroyed and I didn't put on any weight. Benefits are I am now always correct when I have a discussion with the wife.
Before diagnosis and treatment I was visiting the bathroom 3 times a night and this is still the case. It's a combination of that and age that leaves me tired in a morning. Personally I believe most of my lethargy can also be put down to age, I'm 'only' 71 but if you're active at 80 then I would take that as a bonus.
My PSA is <0.08 and I will continue with the hormone injections for another 9 months (2 years in total). I understand once they finish my PSA may increase. Obviously staying in the UK will allow you treatment for free, however I opted to pay and have all my treatment in Thailand (Siriraj Bangkok). Although this is a public hospital the treatment and service has been excellent, and I hate to say this calm and civilised compared to some of the situations I experienced in the UK.
