If you got super stoned before on the same edibles, then you'll probably get super stoned off them again. While you do build a tolerance, it shouldn't have gone up a considerable amount after two prior sessions.
That being said, there should be no reason to increase your dosage if you felt you were adequately stoned the last time you ate the edibles. Unless you feel confident and for sure know you can handle yourself, you should eat the same amount as last time. No need to worry about tolerance.
Also we don't use SWIM on here, a mod is either going to tell you to change it, or they'll close the thread. It doesn't protect you anyways.
