Hi Miss
Best advice I got early on (Day 107 for me, so not that long ago) was "to do whatever is necessary to go to bed sober tonight." For me that meant I had to change some basic things, like going to bed earlier - which was really difficult because I'm a night owl by nature. One of the things I did was force myself to get up at 5:30am and go to the gym. In order to do that, I HAD to be sober the night before. And after a while of working myself into this routine, I HAD to go to bed earlier from sheer exhaustion
I'm not suggesting that you do any of this, Miss. Just hope that you have a solid plan to get you through your evening. Sober Yoga sounds good to me!
