I expect nothing less from Instawallet. Previously, they used to keep private keys in the URL and allowed google to index these URLs. It took a lot of pestering and hand-holding to get this fixed. I should have figured this would have happened sooner or later, given their incompetency regarding security.
I was speaking anecdotally, both from my experiences and the many experiences I've read about online. Modafinil is a great replacement for sleep once in a while, but repeated usage ends up making it useless. It's not that you don't notice the effects, more like you notice the lack of them. Still tired, unable to focus, etc.
