Tincture of Indica two hour before lights out and I do mean out. Downside - Eliminates any dreaming. Upside - Eliminates any PTSD nightmares. I'm a wuss and can't tolerate sublingual torture, hence the two hours. My sweet spot is 3ml of a 38mg/ml THC and half a gram of the stripped bud mixed in yogurt. The slightly paralytic, slightly hallucinogenic sense of well being and euphoria starts kicking in about the 45 minute mark and intensifies to the point of being unable to stay awake at about the two hour. This and learning how to breathe has eliminated my sleep apnea induced insomnia and nightmares. I suggest to anyone not familiar with tincture to start very low and work your way up. Simultaneous projectile vomiting and explosive diarrhea can result from a cannabinoid receptor overload. This is MY experience. Results may vary.
