Long term PPI usage has been shown to result in certain vitamin deficiencies, particularly B12. There's lots of info on this on a Health Unlocked Forum for the PAS. This can have serious consequences - I know first hand.
I feel your pain (literally), having been a lifelong heartburn sufferer. GPs seem oblivious that long-term PPI use is counter-indicated.
@Juniper85 it sounds like we have a similar condition. I haven't had a diagnosis but essentially it's like a mild hiatus hernia, where the valve doesn't close off to your stomach properly. this lets the contents of your stomach leak upwards, or even let the top of your stomach itself into the oesophogus.
I manage ok with just the odd gaviscon tablet nowadays after adjusting my diet to improve gut health. Basically I copied and adapted what Tim Spector at Zoe was doing without paying the extortionate fees!
I had some 'trigger' foods, which would set me off, which I now avoid or have in moderation. These aren't always the usual suspects though, as white flour, bread, pastries, particularly with sugar can be one of mine.
I massively increased my 5 a day to at least 15 and introduced pre biotics such as live yogurt and saurkraut to my diet.
The difference in weeks was amazing. Bloating gone and reflux massively reduced.
I know everything ends up, for good or bad, being attributed to menopause nowadays, but I did once say to my GP, 'What if there's more than one thing going on?' Mindblowing eh?!

Chances are if you had this pre menopause, it's a separate issue.
Couple of other things that help me for sleep are to either sleep on my left - the side my stomach lives on 😄 - or my back, with decent pillow support to keep your head elevated.
Hope that helps - it's a horrible condition.
