Hi Daisi,
The worry for most people with 'alcohol-free' is that it's a step closer to the real thing. Reasonable logic I suppose. There is also a reasonable line of thought that a behaviourist psychologist may use that drinking alcohol-free beer must lead to the extinction of the learned response link betweenthe taste and smell of beer and the physical and mental adiction.
If you're in charge of yourself, and are confident and settled in your sober state I think it's totally down to you how you live with it. If it really is a sneaky step back to the old ways - you will know it, if you're really honest with yourelf.
Personally I think alcohol-free beer is so pants, I'd rather give the local tramp a tongue-bath.
Deg.
