Hi I am currently on lustral 50mg and was wondering if I stopped taking them how long would it take for them to be out of my system?

In brief: TAPER

Must slowly taper off, withdrawing gradually over 2 weeks, to avoid withdrawal symptoms.
The 1/2 life is about 1 day, meaning that 1 day without it results in 1/2 the blood level. The 2nd day is is again half as much. So after 4 days the blood level is 1/16 of day #1. After a week it is only 1/64 as much. After 2 weeks it will be essentially gone.
