Once sober, you definitely have more space to fill. I think that comes in time. At two weeks your brain is still sorta trying to shift gears. I'm just over two months and I notice the changes occur gradually. We addicts our the instant gratification/alter our moods at will sorta beings. It takes time for your body and brain rhythms to find new balance. I try to be gentle with myself in recovery. I know at times I expect too much .too soon of sobriety. It takes times for everything to heal and repair.
