Nintedo DS may cause exhaustion, illness

The culprit: Nintendo's new Crosswords DS game, which also comes with wordsearch and anagram challenges (the latter is perhaps the most addictive, thanks to the rush of satisfaction you get every time you solve one). Of course, I've been starting out on the easy levels on all three games, since writing on the touch screen takes a little getting used to (or at least that's the excuse I'm going with), but I'm sure by this time next week I'll be tackling the higher levels.

So tell me, Pop Watchers, am I alone in my addiction? Which DS games are keeping you up at night? And what other games should I check out? (Yes, that final question is a little scary, but at least I've copped to having a problem, right?)
