Anxiety Medicine Discontinuity. I stop?

Hi, I got Anxiety attack 2 yrs back and started on Pati medicine. Initially 6 months on Pari 25 and then reduced to 20, after 1 year reduced to 10 and 5, then I got again in Jan this year and Doctor advised to continue for some more time. Then I started in 25 for month and on 20 for last 10 months and now on 10 mg for last 10 days. I'm feeling normal after reducing the dose. Just want to check can I stop taking Pari 10 as well after one month? When I checked with my Doctor, He told whenever I feel comfortable reduce the dose for 10 days and stop. But how to know that when I stop I won't get this again? I'm feeling comfortable now on 10 mg from last 10 days. Please suggest when can I stop? Major reason of trying to stop is, I gained 12 Kgs weight in one year due to this tablet.
