Bit of a late reply but maybe future use few tips of mine for amphetamine/stimulant crash.
1st off redosing keeps me going and topped up - but it gets to a point where your burning yourself out so I try and get a minimum of 4 hrs preferably 6+ hrs sleep in a 24 hour period. Next day dosing effects are better than continuous dosing with no rest IMO.
2nd food. You will not feel like eating while speeding but if you force yourself to eat something, even just a banana, your body will be thankful. It still needs fuel even though you don't feel like it! Having food in you eases comedown when it hits IMO.
Finally - HOW to sleep? Don't attempt less than 8 hrs after last dose because you've no chance.
If you can get a script then in order of preference:
Zopiclone - drops you fairly quick, sound sleep, no next day effects other than horrible taste in mouth.
Clonazepam - depending on dose can relax, sedate and drift you off or knock you out. BUT if you wanna dose up on amp again next day I find the amp is less effective.
Diazepam - for me takes high doses to relax me and give me euphoria - however I did not find beneficial to sleep.
Promethazine - rubbish. Virtually paralysed my body, yet mind still active and felt like crap the next day, a lot worse than if I'd just stayed up with nothing.
There are many more prescription and non-prescription sleep aids that can help on comedowns. These are the only ones I've tried and just my opinion on how good they are. They may work better or worse for others. Please be aware Z-drugs and benzos are addictive and tolerance can grow quickly so should you try these they should be used occassionally - if you deal with comedown and sleep naturally this is the best healthiest way IMO, though most folk go a little OTT from time to time and need a helping hand
