Glad you're sleeping better squeaker. Not sleeping is a huge anxiety trigger for me and I've been struggling over the past few weeks with it. Last night, I had an Epsom salts bath for the 1st time and I think it did help, I managed around 5.5 hours on and off, which is the best I've been all week. I'm going to try it again tonight - I have a feeling I'm probably deficient in a few things including magnesium, so hopefully this should help.
I hear you on the compulsive swallowing thing too. That's something I've noticed about myself this week. My reflux has been really bad and I think it might be linked to that, plus anxiety. Hope the Sertraline helps for you - good luck!
