Slightly weird one: I occasionally get what I think is a psychosomatic sinusache. It seems to be induced by looking at a sharp edge or point, and perhaps happens to me once every one or two weeks. I'm wondering if anyone else has ever experienced this, and/or has any input into what's going on (mentally or physically) and any fixes or things that alleviate what's going on. As always, [more inside]

I'm awake by 7 AM, but don't feel truly mentally "awake" and in the "zone" till the afternoon. Caffeine and exercise early in the morning help a little, but mainly they seem to affect my physical energy more than my mental energy. Does anyone else feel this way, and what can I do to get my brain up to speed earlier in the day?

I want to cultivate some good mental exercising habits. For that, I need some good, diverse sources for puzzles and activities. Specifically, I'm looking for, preferably free, sites with a decent database of verbal, logical, spatial, lateral thinking games. The format can be flexible, so crosswords are included. Also, games that test and hone reflexes and reactions are also welcome. Additionally, ADHDers are also advised to stimulate the cerebellum. Any help on that? Basically, I'd like a list of resources for complete brain workout, that can be performed atleast once every day. Obviously, I'm not looking for one site to include all of the above.
