I use to take 40 mg and stopped for a year. Just got back on 20 mg. It’s not working either. It use to work like all day I was so motivated never Depression and now it’s just not helping at all. I do have thyroid issues and a pituitary adenoma but that’s regulated. I don’t even take the Xanax I use to take 3 mg a day. So it’s bizarre to me. Anyone ?
