When I first joined, I spent way too much time and was interfering with my bedtime - and frankly, my hobbies / interests suffered. Had to go cold turkey for a while, like a year, and now I try and manage my time better. I met a lot of nice people here and was enjoying the conversations and meeting new friends so it was hard not to read everything. Now try to keep to about 30 minutes a day average but kinda failing, more like an hour.
