I smoke sporadically throughout the day/week. It usually just depends on my schedule but I'd like to smoke all the damn time, ha, too bad I can't afford that. I've done it for a few days or a week at a time before though and I feel like I'm still mostly the same person I am sober only more personable (if it's a sativa) or just plain more relaxed (both sativa and indica but primarily the latter). So yeah, I'd say I'm the same person blitzed as I am sober, hell, I do my job better baked than I do sober.

One trick I've found for not fucking yourself up too much by letting the green get out of hand is to know someone that can get adderall or rit fairly easily at a good price for you. Whenever you've got shit to do just blow an addy and you'll have your energy and motivation back multiplied by a hell of a lot. When you start comin down (kinda sucks for some people, makes you feel like shit, like coke's little brother... both literally and figuratively) just smoke another bowl, get some food to fill your stomach up after not eating for 5+ hours and to satiate the munchies, and chill or pass the hell out.

cheers
