I'm now in my 9th year.
I'll write another time about the reason I made the switch; I wasn't, at the time, eating much meat or fish and so it was pretty easy.
The thing I wanted to say, at least so far as the UK is concerned, is, at last, retailers understand that there is a market for vegans and even though they don't have a section marked 'vegan', their food labelling now carries the vegan trademark or they tell you it's vegan-friendly.
I know this might not sound like a big deal but it saves me/us heaps of time when we're doing a shop.
The best retailer for vegans — and it's a close-run call — is Aldi.
As to eating out, it's still piss poor and the independents don't get it: being vegan is not a fad and it's not difficult to prepare something other than a limp salad or borning pasta. Get your act/s together, please.
