Dont know if bombing works for 15+g of substance, I barely feel even that, with less I could stop completely. Its always been that way, not acquired tolerance. Guess my best bet is finding a working extraction tek and/or making capsules.
Just noticed that breathing matters a lot with TnW, its important to take a deep breath before, having some water in the mouth, then slowly breathe out while placing the powder and take a deep sip of more water together with swallowing. Most relevant ia not getting any powder into the airways but when sone properly I get little coughing and nausea. Still, its not a good technique.
