6 hours on the water, omg. I have to sort of roll out of the yak to hands and knees to stand up after only two hours. I haven't been lately as its cold now and I really do not want to get bronchitis again which took 2 months to get over this time. In answer to an earlier question on cramps, I do take high dose magnesium and D3 and still manage to get cramps if I don't take potassium or eat bananas. I have a few more months on Tamoxifen yet before it is likely I will be put on Femara. Not fussed if it means another one of those bone scans as they are terrifying for me. I hope your lumps turn out nothing. I have something similar and can only feel it in a certain position but according to scans a few months ago, it is nothing and it hasn't gotten bigger so it must just be a quirk.
