I've been a veggie for c28 years and it's mainly cheese that is stopping me from even considering veganism.
In fact, I'm actually quite annoyed at the recent rise in popularity of veganism as now many places offer vegan dishes where they used to offer vegetarian options, which means either no cheese or weirdo non-cheese. More than once I've ordered a burger that was vegan, but asked for proper cheese instead of the vegan cheese it was listed as coming with.
Anyway, maybe there is light at the end of the cheese-less tunnel...
I haven't eaten meat for two and a half years, not long but I found it very easy to give up.
Giving up cheese would be a struggle for me, I also like eggs and milk in my mug of tea ( typical plumber )
But I do feel vegetarians are now being overlooked in some restaurants.
