some people love it, but they need to up dosages so fast to get same effect, read recently someone taking 4 grams a time due to tolerance, which maybe is tachyphylaxis
with bupre i started with 0,5mg and went up to 8mg per day, relatively fast. every time nasally. with kratom for example i can stay at my standard dose of 5g for months.
