Hi Gailee, welcome to the forum.
It does not make sense to stop HRT at 50, when most people are only just starting it. You should still be on oestrogen to protect your health for the future. Conjugated oestrogen would be Premarin I imagine? What you need is a transdermal method of delivery, such as a patch or gel. These are risk free, much 'safer' than oral delivery as they bypass the liver. Information can be found under treatments on this website, and another excellent resource is Dr Louise Newson's website My Menopause Doctor.
Yes, you will probably go through all the rubbish menopause symptoms if you stop, although may not, of course. We are all different. However, continuing with oestrogen therapy will protect your bones, heart, brain, gut, and genitourinary system for the future, and you can take it for the rest of your life.
