Everyone is different, so I don't know what you mean by 'with a vengeance'. I've never taken anything; I had flashes--they felt like a blast furnace emanating from my core, but they lasted less than a minute and faded quickly. At the height of the occurrences, they happened maybe 10 times a day; I never woke up in a 'puddle' as some people describe, and they never woke me up a night, but I only get about 5 hours of sleep a night, so not much wakes me
They have faded to perhaps one or two a day now. I've completely lost track, but they probably started in 2005 and the worst was probably over in 5-6 years, but those were the years of the infidelity/divorce, so stress was probably a factor. Who knows.
Do you think you could tolerate them in any way, shape or form? Could you dress in layers to accommodate cool down when necessary? Do you need the hormones for any other reason like osteoporosis?
