OK – well first of all congratulations on your recent success, but a word of warning. I have fully quit from cannabis before, though in my case this would be the first time it has not been prompted by some external circumstance. I have also gotten over the initial hump and felt a distinct improvement in clarity, memory etc. In my experience this can almost a high in itself – when you're swimming up to your ears in THC every day, as we have, the upsides of going without are very apparent once you get past the distress of the first week or so. I once saw a comedian very amusingly compare it to acquiring ESP: "hey, I know exactly where my car keys are!" However, after you get over the novelty of ordinary sobriety, you may find (as I have, repeatedly) that as that novel sense fades, you may get hit with a unexpected and possibly profound sense of craving, almost a deep nostalgia for weed. This I have no real insight on, it's a life challenge I suppose and one I have never seriously taken on yet though perhaps I'm starting to now. But I'll advise you to stay alert and look out for that second wave of longing.
Thank you and good luck!
