It's whatever you need to do and what works with you.
I tried them a few weeks back. I didn't mind them.
Over the last month I've been drinking a few bottles of ginger beer everyday. On top of addiction / disease / whatever I have a habit of playing on the laptop and drinking. Drinking a substitute for me keeps my mind of alcohol - for some it may be opposite.
TAKE CARE - most non alcoholic beers have .5% of alcohol or less. Only try true zero alcohol types
