About gall stones

Nearly 3 months ago, I had some days of severe abdominal pain(
shifting pain all over the belly ) following which I felt very weak.
Although, the pain went away but I did not feel normal and
subsequently my daughter noticed yellowness in my eyes. I went to ER
and was diagnosed having bile duct blockage due to gall stones. One
of such stone was crushed using ERCP and I was discharged next day.
Since then I am avoiding saturated fat and refined carbohydrates ( I
am finding it hard to let go white sugar entirely) and I am not
taking any kind of meat or alcohol. I do get these days mild pains
which may be called classified as discomfort. But, Now, My doctor
wants to remove Gall Bladder so that I do not get same kind of
problems again. I want to see how I feel for next few months before I
decide to go under the knife. I am not trying any kind of flush
because it might create the same problem.
Can any one with knowledge or experience let me know whether it is

safe to wait for 6 -8 monthes ? My doctor is absolutely against
this idea whereas I am passing thru such a phase in my life where it
is very important for me and my job to work 6-8 months wihtout any
kind of interruptions, if I may help. Any advice shall b
