Thanks for the tips everyone.
To be honest I am doing well with my food choices, and with not drinking.
The only issue for me is in dealing with the amount of time I have free in the evenings.
The days are okay. I make sure I go on the exercise bike every day and have at least one walk. I've been accepted as a volunteer on Tuesday for the British Heart Foundation and I've applied for a job for 20 hours a week as week.
In the evenings I get by playing Animal Crossing again and using my new-found positivity to enter competions online
Still, at least I don't wake up wondering what I did or said the night before.
