"this drug is terrible.  i am a 13 year old girl and i was put on guanfacine to treat adhd (combined).  i started on 1mg and for the first 3 weeks it was great and then all of a sudden, i started to lose energy at 3:00pm.  i would miss out on softball practice because i was so tired.  to fix this, they decided to put me on 2mg.  it worked for a week but then i became really irritable.  then, i would start getting extremely tired in the afternoon and it was worse than before.  i have schizophrenia as well, so of course i start having hallucinations."
