Letrozole

Hi all, new to this site. Am on Letrozole and feel very guilty as it’s dampening down the hormone Oestrogen, but can honestly say I hate it. Went through the change for 10 years and at 64 I’m going through it even worse. I’m having bad flushes-night sweats stopped. My bones and joints are aching and itchy areas in unusual places. My mood has become short tempered and tearful. I feel so angry all the time. Is anyone else feeling similar ??
