Three and a half years out and exhausted!!

Thanks for your response, iserbrown. First time I have actually posted  but have always been amazed at the amount of support on here. Nobody understands like someone who is walking in the same shoes!! I have just had more blood done too, so I'm hoping they might show  something that can be done to help increase energy levels. I think we do set ourselves high expectations and I think I just need to do as you suggest and just take it slowly. Hope all goes well for you with the change from Tamoxifen. I know it is a great drug,  it helps keep us here but certainly not without its downfalls.
Thanks again for your support,  take care!
