when im out to "roll" on Adderall with my wife, we like to take 60-90mgs orally or rectally, for a nice 4-8hr high, and finally redoes only ONE TIME, and only redose with 30-60mg MAX, we understand it doesn't bring the onset or euphoria back, it just extends the "duration" or just makes u feel normal and avoids the crash, but we mainly take it for spiritual reasons, to help our relationship and such, we have had extreme crying sessions talking on Adderall over the dark side of life (how this addicted robbed us, how CPS took our 2 kids and her mother has custody, how we both had issues growing up) quite a beautiful experience to get past some walls in our relationship..we had extreme happiness and partying (driving, blasting music, talking about everything from politics, our kids, the world, people in our crowd, and etc) we have had the BEST SEX we have ever encountered in our whole life induced by speed, its a mind blowing experience, that helps break down barriers also with our relationship..it just helps us and or commitment to eachother, not to mention it helps us clean, talk, go for long walks, and do whatever things people do tweaked. when we snorted it before, it lasted 40mins, and it felt like a cocaine high where we never were satisfied and became anti social with eachother, that's why im against it. the only times I will snort a little is if I smoke weed with the Adderall, which we usually do for sex, and the weed is weighing down the speeds effects, ill sniif half a pill to boost up quick to perform for sex, or in awkrd situations where the weed is making me paranoid and insecure ill sniff some, but actually now that its mentioned, when we initially take it orally or rectally,. sniffing a little hours after doesn't give me the coked out feeling or wear off in 40mins, it kind of fades and blends in with the oral dose we took...sorry for jum[ing off topic!
