I think it's mostly because my work hours have changed. I used to be up at 6.30 every morning but can now sleep in later most days. But I still wake up when my wife goes to work so it's like WBTB every morning. Also I finally have a steady sleep pattern so am getting a lot more sleep/more regular sleep which is something I never used to have.

Also I've just had constant effort this past few months. RCing every day and keeping a steady dream journal. I used to spend a lot of effort flicking from one technique to another trying to find one that worked but I've found that just RCs and DJs alongside lots of sleep and WBTB seems to really do the trick. Last night I knew I'd get lucid this morning and I did!! I'm hoping for a repeat tomorrow morning!
