Guanfacine
"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."
