Thanks for your early reply. I am seeing the Gastroenterologist this Friday (21st) and will get his diagnosis based on my abdominal scan andendoscopy.
I have been on 3 other groups (in order to gather as much info as I can before seeing cons) - only one person has mentioned gastroparesis but she was on a different cocktail of drugs. It is all individual.
I am trying to gather good info before my appt as I feel I need to go in "fighting" a bit so that the easiest diagnosis (i.e. it IS my drugs) isn't reached before exploring other avenues. Lithium it is stated is the "drug of choice" for bipolar and people are on it for years and years. So surely more websites/articles would have been written about this side effect which disables the stomach. However last night trawling the net yet again I discovered an extract from a long medical research paper that said they were moving away from using Lithium in the long term because ... other drugs are now used and mention of side effects. Drat I cannot find where I saved it now!
If you come across any other info, do let me know. After Friday I'll let you know what they say at the hospital.
Best wishes and have a good week
