Here is a couple of things that we can do to improve our situation with GERD maybe...
A Japan study “Lifestyle factors affecting gastroesophageal reflux disease symptoms: a cross-sectional study of healthy 19864 adults using FSSG scores”
finds two important things:1) Sleep quality is essential for GERD treating
(unfortunately i can’t find exact how long one should sleep in the case of GERD)
It is well-known that nighttime GERD symptoms are the crucial cause of sleep disorders [32,33], but recent studies also suggested that a link between sleep problems and GERD might be bidirectional, for example, due to the influence of sleep stages on esophago-upper esophageal sphincter contractile reflex  or due to reinforcing perception of intra-esophageal acid . Therefore, improving quality of sleep might be essential for relieving GERD symptoms.
(maybe that is why melatonin is promising for treating of GERD?)2) Eating habits – not what you eat, but how you eat!
Accordingly, such dietary habits as the following should be avoided:
1) having dinner a few hours before going to bed (>3 hours),
2) the habit of eating a midnight snack,
3) frequently going without breakfast, and
4) the habit of quick eating.
It should be noteworthy that these four diet-related factors present more significant effects than alcohol or smoking on GERD symptoms.
For me the two main things that is hard to manage is good sleep and early dinner. But i am working hard to improve it.
