This sounds like me, to the letter. The doctor's never said exactly what I have, but I've looked it up myself and I've got the exact same thing you do.

What meds have you tried for it? I take Concerta, and it works fine for me. It's what I've been taking for about eight years now, ever since I first was diagnosed.

Aside from medication, I've found a thing or two that works for me. First, if you have something you need to get done, (along the lines of cleaning the house, or things like that) thinking about things that make me mad help get me out of that sluggish, 'ugh' feeling. Either that, or do just about anything to get your blood pumping. Get your adrenaline flowing, because that helps counteract the problem. It's not always the best solution (since you very well can't read while you're moving around, or stuck in a self-inflicted rage) but it works in some cases. I hate feeling angry, so I don't usually try to tick myself off.

If you're just sitting idle, and you're dealing with the SCT, I recommend playing a video game or going outside and playing sports or something. The video games are actually easy to do, because you're keeping your mind active and interested, and the sports will keep you active, so your adrenaline gets going.
