don't worry Sueness, reaching lucid states is something that can fluctuate dramatically through certain periods of your life...

while i think all that you have recently done is good, in the short term, facing oneself is something that initally can lower your vibration and reduce your ability to reach lucid states--that's in the short term...

in the long term, this will raise your vibration, and likely take you to even higher spiritual heights, as long as you are able to stay true to yourself and your highest aspirations.....but this is a period of challenge, as when we stop mood altering to the extent in which you have described, and lose contact with those worlds, we can become vulnerable to getting caught up in the beliefs of mainstream consciousness...

but as long as you continue and to aspire to reach those worlds, have faith that they will return to you...

since the alcohol goes straight to your pineal gland, that's where the dmt is released in your rem state of sleep. It makes sense that one would have crazier lucid dreams when they have been drinking, since the gland is in shock at the time anyways. I have had several friends tell me that they experience more lucid dreams when they have been drinking as well.

As long as you focus your intent, and keep up with the meditation- even trying to go into a meditation in which you visualize the astral realm before drifting off so you can control your visualizations before you pass out, then go straight into them with the loss of consciousness and drifting off to sleep.

Try drinking some mugwort tea before bed, program a quartz crystal and keep it in your pillow case with the intent upon lucid dreaming.

My bet is you don't get lucid dreams because you sleep better.
Lucid dreams are associated with shallow sleep. Most of the LD's I've had were alcohol-induced. They take place in the early morning, when the tranquilizing effect of alcohol wears off and is replaced by the hangover and shallow sleep.
I don't drink alcohol often and most of my dreams are very deep, adventurous and non-lucid.

The only thing about your experience that seems strange to me is that your regular dreams are dull and uninspiring. Perhaps a dieta of Silene capensis could help you.
