Just start at day 1, and come back every day to post an update. If you relapse just start at day 1 again. If 90 days is too hard try the 7 day first than go to 14 and so on. Im on day 65, first streak, first challange, but it depends on the person and addiction i guess. No matter what challange you take, be strong and keep going at it, you will make it to the end! Good luck brother!
Go next brother. You'll do this! I was in the same situation but now i'm successfully fighting with this addiction. So never give up!
@Harpsichord i think 1 its okay, but it might be become 2 in around 30 minutes again, it is the last time iam doing No PMO
