Possible, but very misguided.
I would heavily advise against this...the purpose of this forum is harm reduction after all. You're certainly, and I'm sure you can intuitively guess this already, not going to be doing your body and internal organs any favor by doing a 2 day binge on x and amps. I mean, come on, if you thought it was a smart idea, why would you go to the trouble of starting a thread and asking people about it???????
If you're going to do x, just do x, that's it - you already have enough health concerns to worry about over doing the x that you shouldn't even be thinking of what other drugs you're planning to do in the future in addition to x. After using x, you should get a good night sleep and keep a healthy diet for a few days. Get yourself stable again...
And besides, the way you're talking about using amps is not the appropriate way to use them - yes, they keep you up and active/focused, like x or coke, but that doesn't make doing amps a good party drug...and if you're going to use amps on top of x, then you have all the relevant concerns about keeping hydrated and monitoring your heartbeat, which will likely get extremely rapid depending on dosing. Keep safe yo, can't say nobody didn't warn you...
