I'm late to this thread but thought I'd put my 2c in! I've been on Genox tamoxifen for nearly a year now. For the first 2 or so months I found I was very easily agitated and what I call 'a bit psycho' in the evenings! Not sure if this was the Genox, me getting over my mastectomy, adjusting to my new life, or the fact that I have 4 kids! But, like I said, I calmed down after a while and now am not half as grumpy as I was. Aside from that, I have had very minimal side effects so far - one ankle gives me grief when I'm on the rowing machine, one of my finger joints is stiff, I have no libido and my hair is thinning but that's about it. I'm fairly active (crossfit 3xweekly, and my work is very active), and young enough (39) so I'm sure that helps. I take my tablets at night. I have met another young mum who was on tamoxifen and had no side effects either, so be encouraged, it is possible!!!! x
