Whether this is something you fancy doing or not I thought I'd share a suggestion. If nothing else its a good exercise in self control, but it could also have health benefits too.
I already dont have milk as I cant digest it
I did it a bit extreme in October and gave up carbohydrates
November I gave up wheat produce and realised I had a mild intolerance e.g bloating when I restarted so Im now on minimal or no wheat/gluten.
January was the classic no alcohol.
February was 'sugar free' feb, no sweets, no fruit etc
March was supposed to be caffeine free but I failed so will try that one again in April.
Doesnt have to be food, could be swearing, smoking, anything really!
