Guanfacine xr

I take 35mg of Adderall but today my doc added guanfacine xr and said to “play with the time that you take it.” I have a little higher bp so we chatted about this. He said that it can help with bp, the lingering hyperactive issues and possibly some sleep issues. I would love to sleep without having to lay there for 3 hours so it would be nice to accomplish that. What have you found is the best? I don’t want to be tired all day so would taking it in the evening around dinner be a better idea?
