Hi Julesy
I smoked weed for 20 years, drank for 15...what you describe was pretty common for me when giving up both (I gave up regular use of weed in 2002, and both booze and pot for good in 2007) but check with your Dr if you're at all worried, ok?
Two weeks is great - but it's very early in the piece - compare a fortnight to 30 years, 15 years...it takes time for mind and body to heal and to get things right.
My new manta is 'change is not an event, it's a process' - it fits here...give it time Julesy
You're doing well
