Tenex | ADHD Information

Has anyone ever tried Tenex with Concerta....my doctor just prescribed it for my son (9) 1mg at night.We used it with Ritilan LA(very similar), calmed her down and we were trying to counteract tics, which it also helped.I have been using Tenex with my son and at first we used it along with concerta.  It really smoothed out the evenings and he slept very well.  (That was not an issue)  Then I weaned off the concerta and now he is doing really well on Tenex alone. We us tenex with the youngest. Originally it was with concerta, now with focalin. There is a very long Tenex thread on this board that has studies and info on using tenex (guanfacine). We started slow at .5mg and worked up to 4mg (2AM, 2 at night).
