Oh Shirley, I'm sorry to hear that the Barrett's esophagus may have progressed to esophageal cancer. Please keep me posted as we have a group here on Connect about esophageal cancer too.

@sparklegram shared that she takes tamoxifen at night. Taking your pill later in the day may help and could be discussed with your oncologist about how best to gradually shift the time of day you take it. I know that it is advised to take it the same time of day, so you wouldn't want to make the drastic change from morning to evening in one day.
