Hi Wolves58, I've been on prostap3 30 months and headaches aren't uncommon, but I don't know anyone who had a light head, as with any side effect, if you have any concerns, contact your team, your cancer nurse specialist CNS is there to support you It's a tough hand we are dealt and the early days are the hardest, meetings and tests, waiting for results and treatment to start, is awful, but it will get easier, I also had radiotherapy RT, 20 months ago, though as there are are a few versions, I had hypofractionated EBRT 20 doses which is the most common, some have 37 cycles, but this is being phased out and has no benefit over 20 cycles. then there is brachytherapy for contained prostate cancer, and SBRT which is only 6 cycles but a higher dose and less side effects, best wishes for the 9th.
