There is also no way you need 2 bowls of 20x..thats rediculous(edit, I wonder if its even real 20x). No offence, but dont waste youre money man. LOTS of people dont get effects the first time, or even the first 5 times..but the reverse tolerancy is real, and it will work I guarantee you if you start low and and try every few days until you break through. Make sure you do it lying down inthe dark, no distracting pulsating music..smooth tonal music is good.
I remember smoking multiple hits of plain leaf years ago getting no effects other than fatigue and headache after..Than I got some 10x and brokethrough to one of the most intense and curious experience of my life to date. It was insane and I totally overdid my dose, just thankfuli even remember part of it. Dont want to discourage you, just suggesting you approach it differently. If you start lower and work youre way up, lowering youre tolerancy slowly, I think it allows you to take more in and build a more secure relationship with this plant..or any plant.
I smoke or quid salvia once or twice a week, often more, and my dosage for a full breakthrough(smoking with proper method) is about 3-400mg(.3g)..not much. I doubt I would even smoke 20x, my tolerance is waaayyy too low.
Also some believe that tolerance is relative to dosage..so with 20x, you could be only developing sensitivity to high dose salvinorin..whereas if one starts off with some plain leaf as first experiences, its like thats the base level dosage that the reverse tolerance curve works at...so less is more with salvia, over time.
