therein may lieth the problem, that you are on the chemmies already.
Tinks, in my divorce I had a virus and stress going on and the consequence of it all was a gallbladder loss (I had started losing weight as well prior to her "announcment"). My sleeping was shot too and my Doc put me on some strong sleep agent (I can't remember what but this was Stateside anyway). Taking those things was awful as they only had effect for about 4 to 5 hours and I felt like the brown stuff warmed up.
I weaned myself off them, when I woke up one night to find I had loss bladder control....
Get yourself off those drugs if you can but ask your Doc.....
