Hi Rocktavius
Welcome
I pretty much what you did for years - did my work - came home got stoned-went to bed - got up, did my work - came home....
I empathise with the irritability - but the only way I know to get through that is...to get through it...
Be conscious that you're gonna be a bear for a while and make allowances for that - it's not fair to bite others heads off.
Above all, reach out for whatever support you can find so as not to turn around and buy a bag and start the process again...
SR is a great site for support - there's also groups out there in the real world like MA (marijuana anonymous) I've never used them tho - they don't seem to be active in my country.
Marijuana Anonymous World Services
Be careful of cross addiction too.
I had the brilliant idea that a few beers would help me in the transition period...the fact I usually post in the alcoholism forum shows you how great that idea was....
