Hi there ~
The medication has a role in reducing your risk for stone formation and gall bladder
as well as liver
disease. You may be improving with regards to your weight due to the same reason. I would advise you to consult your doctor to keep taking the medication or adjust the dosage. I am glad to know that you are liking the fact that you are losing weight and are on the path to recovery with having a regular schedule with exercise as well. I hope this helps.
Take care and have a lovely day!
