Yesterday I was told to go back to taking 1200mg of lithium/day, so I did. Last night after dinner I passed out on the couch! Only slept about two hours (the first block of sleep, got another two in from 1am-3am), but that was definitely an improvement from anxiously passing time until midnight and then being up at 2am. I feel amped, I think I'm going to try going for a run soon, see how my hip does.
Edit: omg, I just realized today is 100 days clean and sober!!!
