@"Kiwi Angel" The list of Letrozole side effects is as long as your arm. They include weight gain, weight loss, anorexia, appetite increase, taste disturbance, indigestion, and, one of my favourites, "general swelling"! As with everything else, you don't get all of them, it's pot luck. What's more, it's a banned substance for athletes because apparently it aids muscle building! #FFS
