How long after dosing did you start experiencing these symptoms? Right away? or after a while? If right away or within a short time, it is possible you got a suboxone pill, or naltrexone even, and it put you in precipitated withdrawal. If it was after a number of hours and you got high initially like an opioid, then you might have just gotten a fent analogue and maybe you're not used to that, and the duration is far shorter, which means you entered withdrawals more quickly than you expected.
It does sound like withdrawal, not like meth. Meth produces euphoria and although it can make you restless, it doesn't have that unpleasant restlessness of withdrawal, it's more like you have a pleasurable restlessness where you don't want to stay still and want to move around. And meth doesn't cause goosebumps or runny nose/watery eyes, either.
Wait a second I misunderstood I think. You're saying you got meth (or were trying to get meth), and it is affecting you like opiate withdrawal instead of like meth? Are you also addicted to opiates right now? If so, then what I wrote above might still be the case.
