Yep. Nic sick only lasts a few minutes to a couple of hours, depending on the amount of nicotine your body can process and on how much you took in. And it starts pretty much immediately after vaping. If you woke up feeling woozy, it's not a nic overdose... too much time since you last vaped. My guess is you're coming down with something, are a bit dehydrated, or just have the occasional morning crud.
