I've been told to steer clear of dairy and highly acidic foods such as fruit, fruit juice, vinegar-based dressings or sauces and tomato.

I have been told the best thing is little and often, with water, with starches making up parts of each meal because this helps line my stomach and neutralise some of the acid but that it will still happen. And that laying flat on my back in bed also causes problems so sleep propped up if possible (which is supposed to also be helpful for reducing puffiness if it's any benefit at all for those of us vain enough to care...)

But the only thing I've found to help is to take medication to reduce the acid my stomach creates which I can get on prescription here (Omeprazole or something like this). Does slow down my digestion and can create havoc for IBS sufferers like myself but it's a toss up between which I'd rather live with.
