Welcome, M, and good to see you. Eighteen years sounds great (I'm heading for 12 myself) and it is hard to find likeminded secular & sober friends, which is why I was happy to find LifeRing.
Sleeplessness is never great and I hope you get a chance to catch up on sleep later. This site is a little slow but others will be along to greet and welcome you. There are also mailing lists and chatrooms as well as other forums in LifeRing.
All the best
