    Or, put more simply, how long before a person would be able to sleep on this dosage?

    SWIMs dexedrine usually lasts for 10 hours, beginning to lessen at around 8. SWIM also has the same problem with sleep and timing the dexedrine. He has tried a couple of things, both which he has found successful. A glass of orange juice or two helps reduce the absorption of the dex (SWIM is assuming that dex and addy act in much the same way). After drinking the juice, he takes 3 5mg melatonin capsules. They don't make you sleepy, but they help regulate the biological clock in the body. Once the melatonin is in the bloodstream, it reacts in the brain to a dark environment. So going to bed about 30-40 minutes after the OJ and the melatonin usually works for SWIM.

    I've been prescribed 40 mg a day for the last 7 months and I have 12 hours where I can really feel it in my system, but after that time i have a crash and go to bed.

    SWIM has been taking 40mg adderall XR for at least 8, and when he first started taking it, he felt it for about 12 hours.

    But because SWIM has been taking it for so long, he doesn't feel very many effects from it anymore, besides the focusing aspect, and if he tries to use it to get high, he can only get strung out on it. And SWIM doesn't want to take more than 120mg because he doesn't feel that's safe.

    So basically, SWIM can fall asleep on speed, but if it is the first time a person takes it, they probably won't be able to.


    Also, SWIM would recommend that a person takes IR if they want to get high off of Adderall. XR doesn't feel as good.

    SWIM can also fall asleep on it. One time he was on a crazy binge and was getting ready to pull another all nighter and took 60 mg but still fell asleep when he went to rest his eyes. tolerance for this drug seems to come pretty fast.

    It depends on a bunch of factors; body weight, tolerence, metabolism, and other things. When swim first started using adderall, it would take him about 12-14 hours to be able to sleep after taking the XR. Now swim can take a nap anytime before or after the peak if he really tries.

    Its definitely tied to tolerance and personal sensitivity. Swim is still able to take a 5mg XR and feel it for a good 6-8 hours, which is basically unheard of. Swim is just super sensitive to anything he takes.

    Thanks for the help Swim'ers. SWIM took a 30 XR at around 9:15, and still doesn't really feel anything. It's been 2 hours or so. Should SWIM expect anything else, or is this dosage just not sufficient for SWIM? He tried 20 mg, and got nothing out of it either.

    SWIM's heart is beating a bit strong, but that's about it. Barely noticable for him, and he's used to that from being a live musician. Don't really notice anything else. Would 60 be something SWIM should try? That's a big increase, but he only has the 30 mg. right now.

    CCApollo added 436 Minutes and 19 Seconds later...

    7 P.M now, didn't notice a thing. No appetite all day. Forced myself to eat just now, and now SWIM feels sick. Stomach problems. Hmm. Should I try 60 tomorrow?

    Psyche recommends SWIM inspect his pills for tampering. Psyche wonders if the small granular type orbs in the capsule have been replaced with powder.

    that's incredibly strange. you may be getting scammed. or maybe its not your drug. Nausea and decreased appetite are common adverse effects but if you're not getting the fun out of them than it may not be for you.

    SWIM is wondering the same thing. Didn't sleep well or eat, but nothing noticeable besides that. Very strange. Started at 10, tried 15, and now 30, with the same results.

    Do most of you swimmers have a high amphetamine tolerance? Swim uses amphetamine relatively rarely and 40mg adderall xr gives him about a 10 hour high, and then another 10(!) hours where he can't sleep. It really can be miserable if he doesn't take it around 6 or 7 am.
