@Cellyk what a cracker, your description of how you perceive you will be on Tamoxifen, goodness I hope you are wrong! Yes I am one of the lucky ones taking Tamoxifen, only got 7 years 10 months to go but hey who's counting! I settled into a routine of taking it early afternoon. Tried morning and evening but I had little niggles, perceived or otherwise, I am not sure, but now happy with my routine. Yes I have a couple of side effects that I can and have to live with but that is to be expected. Try and stay with the same brand, as @Mira had said she found a particular generic brand that didn't suit and I was the same, drove me nutty! I have been using and will stay with the brand Sandoz unless of course the Onc takes me off Tamoxifen and onto something else.
So deep breath and away you go; hopefully your side effects are minimal. Take care xx
