I completely agree man, the reason I started doing dumb shit like that was because I started to get high daily so I had very poor judgement. The once a week thing stopped almoust a month ago. The issue is no longer the tolerance, I just hate the drug now because of how easly it fries the brain and personality, I hope I never take it again.My friend, think of it like this, someone says that a drug is not giving the positive effects it had when they first started using, people that have experience with that drug tell him he should take a decent break to restore the ability to feel those effects again, then that person starts to inject an unpure, non sterile street drug cut with who knows what to keep getting high.
I hope that you would agree that that person is not exercising their best judgement and would absolutely need to stop using that drug for a LONG, LONG time before even considering being close to it.
No judgement and don't be offended but you better smarten up right now before you cause some permanent damage to your body, mind and life.
Hang around and keep letting us know how you are doing.
I recommend you get some 3-4x physical exercise sessions in your weekly routine, eat a clean diet and sleep 7-8 hours every night and avoid all drugs including alcohol to speed up your recovery.
