Your experience sounds a lot like mine. I continue to drink coffee and tea regularly because I enjoy them. They don't keep me awake at all. They do sort of help rouse me from morning grogginess, but I wake up groggy whether or not I drink any caffeine because of digestive and immune issues. FWIW, I've been diagnosed with ADHD (although none of the medications I've tried have been a net benefit) which also makes cannabis an excellent pseudo-stimulant (apparently by slowing down my brain and allowing it to focus).
