I assume you mean the gaviscon advanced, the stuff from the U.K. Yes, I’ve tried it several times, but it causes me horrendous cramping and gas. I wonder if the alginates feed something. I think it’s a great product but I can’t use it.
Its the Gaviscon Extra Strength liquid form, I keep a bottle of it in the fridge for any nighttime reflux.
Those are rare now, the bottle has lasted so long that its expiration date is next month so I will buy a new one soon
