What rehab to do after 6 months of Orgovyx and 38 sessions IMRT?

I have just completed 6 months or Orgovyx and 38 Sessions of IMRT for pcr 3 years after prostatectomy. I am 72, I was doing 30 minutes of elliptical daily up until the last 4 weeks of radiation and have been walking three miles a day. I have acute radiation proctitis and fatigue and the weakness and hot flashes. What are recommendations to gain back testosterone and address the proctitis.
I have been informed that Orgovyx gets out of your system in 3 days. It is the pituitary which instructs your body to produce testosterone and it uses cholesterol to produce the testosterone and this normally occurs in your deep sleep. From this I will be eating items high in cholesterol such as avocados and eggs. I have problems sleeping which I have to overcome. Also when I start to feel stronger I will start weight tracing since micro tears in muscle makes your body want to produce more testosterone.
The proctitis I have been avoiding insoluble food and now that the diarrhea has stopped I started using Metamucil. I continually has gas and my stomach and colon rumble day and night.
Is there anything else I should do to rehab. I am getting a blood test 19 days after I stopped radiation and Orgovyx and every month thereafter. While these blood test include testosterone and PSA, my test looking at PSA is 4 months out. I appreciate any suggestions you can give me. I am starting a new part to rehab but watching the PSA is not new. Best wishes everyone.
