Stimulants How long before amphetamine starts to wear off

For a big night out I'd like to not start coming down off a dose of amphetamine until very shortly before going back home or to chill out at a friends house. Due to other factors like tiredness and alcohol consumption I've never been able to tell how long the plateau lasts and how quickly it starts to wear off after that. A graph like they have for some drugs on erowid (but not amphetamine) would be great. I know there are two main types of amphetamine (not including meth) is there much difference between them?
 
If you're talking about amphetamines like adderall, vyvanse, and dexedrine, you'll be fine in terms of duration. for me all three last a minimum of 6-8 hours. Adderall and dexedrine have 2 forms; the immediate release forms last 6-8 hours for me, and the XR last about 10 IMO. The vyvanse is a prodrug slowly digested by the liver, so it tends to last around 12 hours for me.
In terms of differences, the vyvanse and dexedrine are pure dextroamphetamine. I find it to be pretty mild when it comes to physical stimulation, and gives a strong and euphoric head "stim high." Adderall is a racemix of about 4 amps, one of which is levoamphetamine, which tends to be strictly physically stimulating. I find that it keeps me physically stimulated and energetic much better than dextroamphetamine (vyvanse/dexedrine), but some people dislike that.

IMO, you'll be fine about the amps lasting the entirety of your socializing. They are much longer lasting than things like cocaine. I find them very euphoric, regardless of what form you get it in (dexamp or others).
 
what is the dose and what brand (or if its street amphetamine sulphate, specify) because those all factor in. it could be anywhere from 1 hour to 5 hours until you start coming down. also please tell us how much experience you have with stimulants/what your tolerance is. theres no way to know forsure unless you give all the information needed.

if youre talking about meth, than i can tell you about duration: if youre smoking it, you will be going strong for 30 minutes and then you will be "high" for about 3 hours; i never feel anything past the 30 minutes, personally, but many users report a high that exists after the rush, usually lasting about 2 hours, and then coming down slightly for the next two hours, and after that you start to go below baseline, and you keep going, making you feel increasingly shitty for 12+ hours. if you snort it youll be high for 3 hours, and come down for 1 hour, and then youll crash until you go to sleep. if you take orally, youll be up all night.

d-amphetamine half-life 6-10 hr
l-amphetamine half-life ~13hr

IR d-amphetamine lasts about 4-6 hrs, l-amphetamine a little more. it also depends how much you take.

l-amph doesn't have any good effect in attention or euphoria, more on heart rate and blood pressure. physical stimulation/anxiety.
d-amph is the one produces euphoria, motivation, attention with no or little anxiety

hope that helps.
 
Whats meths duration? I usually use Seroquel but twice when i had run out i was still going 30 hours after the last dose, it was fucking wierd, still feeling good, huge pupils.
Sorry, not trying to hijack, just wandering if oral doses can last this long?
 
Thanks for replies so far and its street amphetamine. I used to take it a lot (most days for about 2 months) two years ago, used about every weekend or every other weekend for a while and now currently use every couple of weeks. I know it sounds like I should be a ble to answer my own question lol but I've found other factors have always got in the way of actually knowing how much is in my system. I would find that if I had a lot when I woke up (usually around half 6) I would be most hyped around midday when I had woken up enough, possibly a little hyped the next day but also tired and tiredest the day after (this is assuming quite a large dose, not sure exactly how much though). Why I want to know specifically when the plateau ends, or if the whole time is a gradual comedown, is so that, like the night I posted this thread I can decide that since I would be socialising until about 2am I might as well take it at 6:30 so I could enjoy it a bit before going out and only lose out on the plateau continuing when I wanted to be asleep anyway. It was just a dab but I think I timed it right :) although my ability to not have trouble getting to sleep and not waking up in the night may have been more to do with the alcohol, weed and etizolam I had consumed throughout the night, likewise these may have hidden the fact I would have otherwise been noticeably coming down towards the end of the night
