If you told your GP that you aren't going to take HRT maybe he/she recommended something less along those lines? Only you know what was discussed at the appt..
HRT does what it says on the tin, replaces some hormones that the body may still require. Eases symptoms. Some ladies don't require it, I have to use treatment for vaginal atrophy - do read the threads about *that* on here ! - otherwise .........
Maybe keep a mood/food/symptom diary and jot down what you decide to try. Give each product 3 months and don't use too many combinations or your body won't know whether it's flying a bike or riding a kite
Maybe decide which symptom you would like to ease first and do a 'search' on here to see how others have coped?
