You'll be okay. Nanners and P-Fit have great advice about
the meds. Regarding your slouching, for me, the rib muscles in the back get sore, then, of course, the same muscles are sore all the way around to the front. That could be what you're experiencing, and if so, it is just sore muscles.
Hang in there, and keep working with your program. HA is awful, and it seems like it yo-yos back and forth rather than letting feel we've made permanent progress. The fact is, though, that every new tool we develop makes us stronger to deal with the next go-round.
