Hmm interesting. I used suboxone for a couple years, quit a couple weeks ago too. I dont get the hot flashes, but I do get leg cramps and other sucky symptoms. I discovered an OTC that actually helps the milder symptoms that last a bit longer. Its called Tranquil day calming formula "caplets help relax and reduce occasional simple nervousness, tension, restlesness, and related irritability", its a mix of hops extract, valerian extract, and magnesium.
