The salt never did anything for me.
I work during the day, so I plan my lax. teas around that schedule.
I drink a stronger ( all senna) tea @ noon, which works in about 4-5 hours.
then I drink a reg herbal lax tea every night before bed (takes 6-12hours).
This works out so that i "go" once in the morning, and once in the evening ( twice a day)
