bipolar disorde
"I'm 46 and suffer from serious bipolar 1 with PTSD from a 25 year old military accident where a live missile fell off an F-4 and smashed my left foot.  Many nights spent laying awake wishing it had exploded. First took lithium back in 1999 and found that it helped, but it was also dulling the positive receptors as well. It would upset my stomach and dehydrate me terribly.  After going on and off of it for years, I recently had a nurse practitioner switch me to the lithium carbonate ER  (extended release).  I now take the whole dose before bed and don't have the upset stomach anymore.  Still thirsty and on the numb side.... but functioning better."
