Hi Cawwie,
Me too,
I am diabetic and have to visit the loo more often than most.
I have found that if I go before commencing SFQ and make one of my intentions to complete it in comfort - that works for me.
You may also need to take some action to strengthen your pelvic floor muscles by doing some appropriate exercise. There are a lot of web sites with suitable exercises for males and females.
Love and light,
Faune
