Haha don’t do what i did.
Came home the day i had it done, knew i would struggle going loo so i took 2 senna straight away, that night i thought i would take another 2 just incase, so i did. The next morning the senna hadn’t worked so i took another 2. All in all i took 6 senna.
An hour later i spent the next 2 days running to the loo, the 6 senna decided to kick in all at once, not good lol.
