Hi bohemian, thanks for replying. It's not so much a matter of sleepio kicking in, it's more of a slow and steady improvement, although there are ups and downs on the way. The first 2 weeks of the 6 week programme, you just fill in a sleep diary, then based on the times you are sleeping, they work out your sleep schedule. For instance, I was sleeping about 3 hours, so I was given a 'sleep window' of 1am to 6am. I was used to being in bed 8-10 hours, lying there awake, so it was a big change having to get up after 5 hours. I started to sleep more, up to 4 hours, after about 10 nights I think. Then it was a bit more each night, and generally feeling better during the day. I also noticed my general anxiety diminishing, which is wonderful. It's really worth going into the sleepio.com site and having a look.
