Addiction is a very heavy word bro. I don't think you are addicted - not yet anyway.
Sounds more you are doing something you enjoy a lot, and probably doing it too much.
5 times a week as a once off thing or once or twice a year is OK; but not as a regular thing.
No need to panic or try to cut it out altogether; that will just stress you out.
Just cut it down three times a week and then twice a week - you will actually look forward to your punts a lot more and enjoy them a lot more.
Punting should always be something exciting and fun and something to look forward to.
If it just becomes part of your daily routine then you are on a slippery downward slope to becoming addicted and enjoying it a lot less.
So, punt less and enjoy more!
