The last 2 years, caffeine gives me hot flashes, sometimes so bad that I feel similar to drowning. I am perimenopausal but without caffeine, no hot flashes. AAF takes the hot flashes way down to where I’m sweating but don’t have the uncomfortable, near panicky feeling of drowning. I also noticed that I handle mental stress a lot better. I’ve only been taking 2 around dinner time, would ramp it up if the product cost less. 4 stars because of the benefits I experience.
