In my first few years, I always need someone around me to help emptying the leg bag (only 500cc) when it was full for every couple of hours. Sometimes it is done in accessible toilet or use a one time big paper cup or bottle to hold and pour out or just drain at drainage in back street. It is very annoying to both me and my support worker. In the night time, the leg bag is connected to a bigger capped bottle or draining to hold overnight.
One day, I saw a lady connecting the leg bag (500cc) to a night bag (2000cc) so that 2500cc can be hold in daytime. I immediately order some reusable night bag and copy it. Since then, my life is free from going to toilet and going out with an assistant.
