Are you taking the guanfacine in the morning or at night and is it XR or ER (extended release)? I ask because I started it last month and recovered a LOT of my brain function, but it is causing insomnia halfway through the night, which of course covid does too, but I'm thinking there may be better ways for me to take it. As far as medical care dealing with that, they are not available unless I am near death. I take the NAC also.
