That's encouraging. Maybe I don't need to be so afraid of trying out caffeine if I just go right back to sleep and don't push my luck on WBTB length.

In fact, I've been doing that when I get the chance to take galantamine and it at least seems to be okay. I mean, if I do the ultra-short WBTB I'm committing to DILD or maybe DEILD, but it's very useful in particular on those nights when I'm just not sure I've got the time for a long, leisurely WBTB like I'd usually prefer. I DILD most of the time anyway!
