I am a 58 year old woman who had a hysterectomy in 1994. I have been on HRT ever since and would like to get off of it. I talked to my dr. recently and she suggested I wean off of the HRT. I started the process a week ago and so far so good except I have been very tired all week. Is this a side affect and will it ease as I wean off of the HRT. Also, what else can I expect to expereince? Weight Gain, mood swings, Hot flashes?
