Most of the times I take Amp (European street speed paste) I will usually start experiencing symptoms of vasoconstriction throughout the night. The first thing I'll notice is a weird pressure in my head and over the next hours my limbs start getting tingly and whenever I stand up quickly, I almost faint. My ears start buzzing. At this point a bad headache usually appears and sometimes it lasts a day or two and in this period I can barely get out of bed because it gets so bad that each time I get up I feel like I'll faint. This is the worst part. I can't eat and even have trouble drinking water. But then, this only happens with some batches of Amp, others will not cause any of these symptoms and I will be good the next day even without sleeping. Could this be caused by something it's cut with? Even tho this usually happens if the Amp is good stuff and small amounts do the job, but those shitty ones that take huge amounts to even feel them don't seem to cause this problem. Idk, it's just so random.

Anyhow, please share whatever comes to your mind about a potential reason this would happen. Also, can you guys recommend some other supplements or anything that could potentionally lower the risk of vasoconstriction? Or anything that's beneficial to take with Amp to reduce any other negative side effects?

Thanks a lot!
