Hi Michaela
I've been on Tamoxifen for 11 months now and counting down to my completion of 10 years.
My Oncologist had suggested that side effects are apparent in the first month and after that they should settle. For me it is hot flashes, slight nausea and aching bones however as I am also on other medication it is hard to say that it is all Tamoxifen's doing. If I think about it I'd blame the aching bones and the hot flashes on Tamoxifen.
I was suffering from dizziness however that is unrelated to Tamoxifen. Do you have other health issues that dizziness could be attributed to? For me it is an under active thyroid, which has only become apparent during this BC journey and is now under control and readings back in the normal range.
Wishing you wellness with your treatment. Take care
Christine
