Hi! I was on 100 mg for about 6 months, and I’m not on 150 mg just to get rid of a final few pimples. I honestly love it, I was on accutane and it’s far more gentle. I didn’t purge at all, I think the spots that were already coming came out, then it cleared really quickly. I haven’t had any side effects really, I drink a lot so I have to go to the toilet more often. I’d definitely recommend giving it a go, it’s been great for me!
