It can definitely damage your stomach Jules, it MUST NOT be taken on an empty stomach, supermarkets shouldn't be allowed to sell it,although it's only the 200mg you'll see on the shelves,which only means you take 2 instead of 1 of the 400mg . I have gut issues too and I never use it 🤷♀️
I know. A GP actually told me to take it when I had flu and told me to take omeprazole with it. That didn't help.
