My ds was like yours after the stimulant wore off. We've added guanfacine (generic for tenex), and that's helped with the impulsivity and hyperactivity at nighttime. It does not help with focus. It hasn't made our evenings perfect, but they are substantially better.
I wouldn't recommend adding too many medicines at once, so I'm afraid you may be stuck with the rebound for awhile. Maybe try low-keyed stuff like extra computer time or TV time at night to help keep things calm?
Edited to add: Some people do a booster dose of the stimulant in the late afternoon to make the evenings go better. That wasn't an option for my child because he needs the stimulant to wear off in order to help him eat at night.
Mom2ADHDboy39313.8243171296Thanks! Rebound has gotten better, I gave him some Melatonin tonightMy son has been on a stimulant for over 5 months and there is a rebound that starts at about six. Another side effect of using stimulants is difficulty to fall asleep. So, what I do is give him a very low dose of melatonin at the time he starts feeling very restless and he ends up getting quieter and falls asleep at about 8 to 8:30. This is a very personal idea that has worked for me; I have to admit that he shows rebound but I think it isn't that bad as of what I have read here many times. If I don't use the melatonin it could be 11pm and still he would be awake with lots of energy.
I suggest you to talk with the doc and tell him about your concern; maybe there is something that can be done to lighten the rebound.
Where do I get melatonin? Are any brands better than others?
you'll find it at any drugstore over the counter, and I don't really have a favorite brand, I always get the one that offers the best deal. Melatonin is a natural sleeping aid. Better call the doc first.
Good luck!!
