Anyone taking Qsymia?

My doctor offered me this today. I haven't done too much research yet apart from knowing my insurance does not cover it. Apparently you have to do it through mail order and have a credit card on file to get started? Sounds super complicated to me, and I took accutane which was an exercise in why healthcare costs so much- lots of covering ones butt rather than patient responsibility. Anyway- has anyone taken this or have an idea how much it costs or if it's worth it? Apparently Express Scripts covers it now- so maybe more insurers will eventually?
