You just answered your question on why you can't get high anymore. Sounds like you will have to take a T break if you ever want the magic back.
We like to keep this sub forum dedicated to harm reduction and your post is more of a I'm pissed because I just wasted my money on 2 grams.
I'm gonna move this over to our Drug Culture forum where members will relate to the difficulty of getting high when we have saturated our receptors so badly that the drugs just don't work anymore. 26 years is a long time to use. Have you ever taken a break before?
