I first of all will assume you are religously doing kegal exercises several times a day. This is important.
Secondly, even tho it makes you leak, regular walking is helpful.
It took me 8 months to get dry. I was leaking multiple pad a day. I work in the service business with industrial customers, and leaking was a real problem. I went to a Cunnigham clamp during the day. I did my kegals, and at night, took the clamp off.
I think the fact you are dry at night is a good sign. The fact you can hold urine while sitting is good. Now you just need to train those muscles to help you while standing and walking.
Kegaling is a drag, but it does help. You might evan google some kegal sights for some different techniques.
