Just my experience, i moved to a new country, new job and loadsa hassle at 5 months sober, yes i did ask my sponsor and he was ok with it, i had done all the AA steps and had a spiritual awakening, a couple of my friends haven't but came in at the same time as me and decided to take jobs round the corner with less stress, they have more time to themselves for meetings, yoga, whatever they need...depends on how you feel and what you are relying on to stay sober i guess?! I certainly wouldn't like to give any advice, but wish you well in your choice:-)
