Congratulations on your first steps! I suggest taking some harmalas (like syrian rue) to soften the trip. I believe that the vivid images and the trickster entities you encounter are mainly a distraction and if you keep your mind clear and retain your intention to go through, you can reach a spiritual level where there is space for insight and growth. If you're physically or mentally worn out, it's difficult to keep sufficient determination and the world may become taunting.
You could try listening to positive suggestions while taking the dose. Somebody here recommended this one and I've been enjoying it:

You can reduce the nausea by the way by applying lemon essential oil on your skin. It's a 5-HT3 antagonist, the serotonin receptor responsible for the nausea reaction. The oral-dmt (with maoi) is worth experiencing. The nausea is tolerable especially the first time when there is so much else to pay attention to.
Good luck keeping the alcohol down! I managed to cut my own use by switching first to low alcohol beer and then non-alc beer to break the habit. Doing anything that distracts from the cravings is much easier than focusing on "not drinking".
