Aw Cath, I fully sympathise. I wrongly assumed I had coeliac disease when I fell in love with baking - given my Mum has CD it seemed like I was making myself ill. When I cut out the gluten it did help with my sleeping patterns weirdly, I think gluten is just really hard for most people to deal with every day!
Anyhow, ground almonds are new best friends when it comes to baking and there’s loads of other flours out there (I like sorghum and mix it about 50/50 with regular supermarket gluten free blend for baking cakes/biscuits).
The warburtons GF sandwich squares are pretty good. Warning, here are still some truly rotten loaves out there… it’s when they taste sweet (allegedly savoury ones) that I can’t stand them. On the more pricey side, Tesco Finest have some VERY good GF biccies (rasperry and white chocolate ) and M&S do GF stuffing and GF ‘breaded’ chicken and fish. Plus their sausages/burgers are well labelled and mostly GF.
I’m lucky that I’m gluten intolerant and don’t have CD… but the jury’s still out on Crohns! Regardless, I barely ever eat gluten now and on the rare times I do, I will be asleep til gone lunchtime the next day.
Our local chip shop does GF fish and chips on a Monday, it’s better than normal stuff. Apparently they clean the fryers out during the day so no cross contamination etc.
You will find stuff to suit you and some of it’s better - I’m on cider vinegar, better than malt
