Stimulants What causes an 'odd' meth high?

[flowersonfire]

So I had a weird experience with IV meth. I took my shot, had a pretty darn good rush, but as the rush subsided, I didn't feel the amped up energy feeling that usually sticks with me for 6 - 8 hrs (sometimes more) I just feel pretty 'normal'. If anything, it's usually the other way around. No great rush, but feel amped and energetic all day / night.
Does anyone have any ideas on what causes a reaction like this?

Tolerance.

Not sure how often you're using but enjoy the rush while you can because that heads out the door pretty fast as well.

I had the same super power supply forever as all the sudden one time it was way different. No Big Bang when the first line finally cleared my sinuses. I had a rush and stayed up a long time as always but it's like it had all the bad side effects of my beloved Tina. Sweat like hell and couldn't breath good. I could eat with no problems at all. Never seen that before. Anyway I guess one n a while u get a change up so u just gotta roll with it. I use a couple times a week for a few weeks and tak a week or two off. It's super easy to raise ur tolerance. Anyway wait till next batch and see what that one does. That's what I'm doin. Good luck.
