Exactly, just like how stopping smoking herb clears you up & refreshes you for that "first time around again" low-tolerance toke, the mind needs to heal/refresh itself from trips, too. There is such a thing as over-doing it, even though the fine line for individuals seems to vary.....sometimes its good to just clear your mind and allow your brain time to recover.
I've been trying to sleep all night, no luck on that....Damn insomnia.....Have a puff or 2 for me, would ya?all this negativity i need another joint.
