Hi,
I have a son who takes clonidine for anxiety and tics and it works well but we can only give it to him at night because it makes him sleepy. When we thought it really only helped him with sleep (will not sleep without it) we ran out for a week and wow, we realized it helped him more than we knew lol.
But I tried giving it to hm in the morning and we had to stop because he would fall asleep at school. So he only takes it at night now.
My other son takes Topamax due to migraines and mood. He is doing FANTASTIC! Don't worry yourself about the side effects untill you try it because not everyone gets the language problem side effect with it. I asked my son after awhile if he was having problems thinking of his words and he said "Yes,....... but I have always had that problem mom". As far as I see it is no worse than it has ever been for him and the mood stabilizer has been a wonderful success.
If you do decide to go with topomax, just remember, you can always take him off without long lasting damage or anything. Things will just go back to before and no harm done.
I would say try it.
