It might just be the fear.
If you start to get the fear, your fucked. I won't let my head go there no matter how high I am. If I can't hear, or hear bells, I groove off of it because I know I'm good and high.
I have never gone blind from smoking. I've stood up too fast when sober, and passed out. I can't stand up fast when I'm faded. Occasionally I can't stand up at all, which is the best feeling in the world, imho. But if I'm sitting and smoking fatties one after the other, I don't do anything fast. If I need to get up I don't get up fast. I can't get up fast.
Actually I will roll around and laugh and forget what I was going to get up for anyway and just stay the fuck on the floor.
Maybe you just got higher than you have been before and got the fear.
Don't smoke so much at one time. Once you get the fear its hard to get rid of it. You'll start to get the fear just thinking about getting the fear.
Stop smoking as soon as you feel the effects of the marijuana and do a compare/contrast graphic organizer, sober vs high.
When the mj wears off, work on the sober side of your graphic. Pay attention to what weed makes you feel like, inside and out. A little chronic goes a long way and I think you took too much, man. You took too much.
You have to know what the stuff does to you personally. You need to know how it feels to be two hits high. You need to be able to tell the difference and even be able to explain the difference between a two hit high and a four hit high. Four hits of good chronic will see you right. There's no point in wasting weed. Smoke a little. Have a few hits and stop. Look around. Notice what happens.
Four BOWLS of good chronic is a night in heaven for me personally. I can still see, but I've been asked, "Can you see?" because my eyelids get so heavy. Maybe your eyelids just shut.
I'm off weed because I am in training to be a pharm tech and we get random tests.
I miss it so.....
I'd give anything to be on the floor with my eyes half shut and my ears ringing.
