You're probably still de-toxing. There may even still be drugs in your system. I don't know what your DOC is, but I remember "go fast" would still kick in days after I last smoked it.
Give it some time. Let your body find it's equilibrium,
BTW, I'm glad you're optomistic, and not trying to drag you down. I'm just pointing out that the fog most likely hasn't lifted yet. I wouldn't trust anything your head tells you. Good OR bad.
