Hmm... well i rarely get nausea from speed, and have no clue what kind of paste you have. but from my experience using mamp and other amps, to me it sounds like unless your nausea is caused by something else, its hopefully just a byproduct of being amped up.
I dont know what kinda Pharms you have? I mean in terms of prescription meds, but many (if not all) GABA analogues would help, such as Gabapentin or Lyrica. Or some of the infamous Benzos! Preferably a longer acting one if you choose, but the sweet and lovely Xanax is never a bad choice. Its no mystery to me why its most people's favorite benzo, including mine. it is indeed the strongest and most potent (excluding Barbs which aren't Benzos anyways). But Klonopin and Vallium would be excellent choices, or even Soma or Ambien too. There is also alcohol, or OTC antihistamines. Otherwise i dont know what kinda Nausea symptom you have? I have never been a big fan of Alcohol. But Hydroxyzine (Vistaril/Atarax) preferably Vistaril, will help with sedation and nausea/ motion sickness for de-amping yourself so to speak. otherwise things like Diphenhydramine/Dimenhydrinate (Benadryl/Dramamine) work wonders too.
Other questions to ask yourself which might help would be, How much experience do you have with speedy drugs, like coke and mdma as well as all sorts of amps? How recently have you done some speed. Also, If its not nausea from how your body is handling your speed, how certain are you that it isn't possibly dirty speed? There are some various testing methods you can look into. I am assuming your nausea is gone by now, but if it comes back every time you do more of your speed paste, any of those questions might lead you to a direct answer, otherwise it might have been nausea from low tolerance level, or something unrelated to your speed all together, and was more a matter of interesting timing that led you to believe it was the speed.
There is tons of digging to be done on this sorta subject through the internet, but I am hoping your nausea is simply induced by being amped up. In which case you should know if you havent done anymore speed in a while. At least 4-6 Hours should be plenty time to notice any gradual decrease of nausea depending the quality of your speed and your tolerance level. That's just my two cents off the top of my head, hoping that its not something more complicated. It could always be dirty speed, which can potentially add a lot more to the equation.
Anyways, Hope that helps! best of luck to ya!
EDIT:(You may already know this, but being that i suggested benzos for a possible solution, and if it works, the possibility you do speed all the time and end up taking lots of benzos, i really feel i must say this!)
In regards to Benzos: If you find every time you do speed, either if its from dirty speed or your bodies reaction to any kind of speed, and you choose to counter it with a benzo, make sure you dont take benzos all the time, or for too long! If you start having side effects/ Withdrawal symptoms from the Benzos, that is a sure sign that you have developed a dependence, and in any regards (weather cold turkey quitting is an option or not) I highly suggest IMMEDIATELY tapering off and giving a big break for a while. Benzos, specifically in my case Xanax Withdrawals, Can be Very Deadly! I am not completely sure if this applies to all benzos but i think so, the fact that for at least Xanax withdrawals, they can be worse than Heroin withdrawals and unlike Heroin withdrawals that WONT kill you, Xanax withdrawals actually WILL KILL YOU! and if they dont the first seizure, they might the next one, and those will keep coming until your off. And even being off of Benzos, if you have taken them long enough, the way Benzos are not stored in your Body's fat cells but actually inside your bones, you could potentially have enough long-term concentrations of benzos leaching out that can give you more seizures, AFTER you have been tapered and detoxed all the way off! Big Word of CAUTION with the Benzos on my part. and Also stuff like Lyrica, and other nonbenzodiazepines like Ambien etc, will give seizures as well.
