You have almost all convinced me to ask my doctor about hrt. Because perimenopause is a bitca.
In addition to helping with hot flashes and mood, hrt has substantial long-term benefits on heart health and bone strength when you start it in perimenopause. It can help joint pain, too (fingers crossed).
Just in the past few days, my mood has improved so much that I hadn't realized how much it had dropped, or how long it had been this low (a long damn time). It's like switching from an older TV to an HD TV. Everything is just brighter and sparklier.
