Looks really promising for people who don't like stimulants or can't take them for other reasons, slowly gaining popularity as well. Unfortunately not yet approved for adults in Europe, or I would have tried it. I'm fine with stimulants, but I'm a little wary of the effects on heart health over decades and I would like my appetite back. I also dislike that with stimulants I don't have any attention span in the evening, guanfacine provides more of a steady effect from what I can tell.
