Well, are your edibles something youre making on your own, or are they in package with the exact thc amount labelled? You could be taking too high of a dose. Its common with edibles to overshoot the amount you actually need fornthe desired effects and wind up feeling sick. Either way if you’re making your own or not, try cutting the amount you take in half and see how that goes. Easier to measure if prepackaged though.
There is also something called cannabinoid hyperemesis syndrome which is possible in your case. Its been shown in limited studies that antipsychotics like haliperidol and olanazapine can relieve symptoms completely. Benzos and regular antiemetics like gravol can help. So can a hot shower.
Main line of defense would be to reduce or stop using pot though if its making you feel this way.
