I've gotten lucid several times so far - mostly from DILDs, but a few DEILDs, too. However, every time it happens, I immediately experience massive fatigue in the dream, making it incredibly difficult to keep my eyes open. This feeling builds until A) I can't keep my eyes open any longer, resulting in me waking up, or B) I try to keep my eyes open so hard I end up opening my real eyes, resulting in me waking up. No LD I've had has lasted longer than ten seconds before one of these two things happens, and so far nothing I've done has helped. Is this a common problem? Anyone know how to fix it?
