cooleymd, I'll say once more, the dosages you're taking are really massive. I warn anybody else not to go near 30-90mg of melatonin, 1mg is sufficient for sleep and 3-5mg or so sufficient for REM suppression. It's also a good idea to give your body a chance to flush everything out and recover equilibrium before taking more, several days at least I'd think.

In terms of "getting good at DEILD," DEILD is very much a "grab the chance when you can" LD method, when the stars all align. I'm a bit skeptical of being able to produce consistent, regular, "DEILD on command" on a nightly basis, but maybe I just haven't figured it out yet, or my sleep style just does not accommodate frequent DEILD opportunities. DEILD works best when you're in a "100% REM" mode, like late morning at the end of your sleep period, where you can fall instantly into REM, or of course when you're exiting a lucid dream where you're already conscious and aware of what's happening (a dream ending) and can prepare yourself mentally for the transition back into a dream.

It is true that focusing on DEILD comes at increased risk of losing recall. Maybe designated certain nights DEILD nights and certain nights recall nights to make sure you maintain good recall.

I guess I'm trying to say: you can do things to maximize DEILD success, and just practice a lot, but relying on it as your sole LD approach may be disappointing. The really successful LDers use all approaches (DILD, WILD, DEILD), choosing the one appropriate for the conditions of the moment. Making the right choice and being successful at it comes with lots and lots of experiments and patience and experience.
