Were you taking Strattera? I took it for awhile, did not help with my ADHD, made me super moody all day. I switched to Concerta after about 6 months and noticed an immediate difference, so much was I proved. The only downside is I would crash hard around 4pm and I'd be grumpy for a few hours. My psych added a Ritalin booster for me to take around 2PM if I had plans in the afternoon, but ultimately I switched to Adderall ER and that so far has done the trick.
