I think that sometimes the days can drag, but collectively, they build up faster than you know it - I've been on it for 3 and a half weeks almost without noticing now!
If it helps, I keep a small handwritten "calandar", laid out in a 7-day grid, from start date to proposed finished date, and cross off each day before I go to sleep. It's slow at first but when you see those crosses on the page building up, it's such a proud feeling! Good luck x
