The good thing is that you have admitted that you have a problem.
Once that important step has been taken there are support services that can help you.
Alternatively you can do it alone, it requires more self control but is ultimatley more satifying.
Try and go out on your bike and just have fun.
Then try to cycle without the phone / garmin occasionally
Before you know it then you will be an Ex Strava addict…….but you must never go back!
