Early Days on Letrozole

A friend of mine recently mentioned that she regularly took electrolytes to help with cramping and as that had been happening to me at that time i thought it was worth thinking about. I am at the gym 3 times a week and I make up a 600ml bottle of hydralyte to take with me and it disappears very quickly. But if i also have a diarrhea episode which for me can happen often due to my dodgy digestive system, thanks to Crohn's disease, my cramping would ramp up to unbearable levels. But since making sure to take gastrolyte/hydralyte after an episode i don't get the cramping. So i assumed that my electrolyte levels had dropped to a point because of my digestive system going awol and was losing more fluid. I figure if it works do it. Just be aware that anastrozole is similar in make up to letrozole but exemestane is steroid based. I was talking to my Onco about this last time because of my cholesterol levels but as they have rectified themselves through diet and exercise I'm sticking with the letrozole. Better the devil you know...sort of...
