Hugs for the rough night.
Reflux usually flares up at night. For us personally it was in the evening hours from 7-11pm. I used to call 7pm 'Witching Hour' and it was pretty predictable.
Glad to hear that you're getting in to your Doctor on Monday, and I hope you get results quickly. I never had the opportunity to try an osteopath, although I have a friend who swears by it.
