For some people not drinking for a month is o problem at all. For others it is a challenge. For some people doing a 50 mile cycle for charity would be a challenge. For most of us we could do 50 miles this afternoon. Everyone’s different.
I think it’s a good thing. I used to be cynical about these sponsored events as I was of the opinion “Well why not just give money regardless”. However I realised that people are more likely to give if they are actually asked.
That said, being dry in January isn’t for me. I’ll certainly be cutting back quite a bit, but I have a few social events on that I know will be more enjoyable with a few beers. If you are going totally dry though then well done, good luck and enjoy February 1st!
