You can order the product OP is talking about from the American Amazon storefront, and actually pay a little less than the one available on the Canadian store. Not by much, but if you want to order and try the product, I recommend doing it that way!

If anyone is going to look into FODMAPs I highly recommend using this book and following to the letter. It groups them and likely only a couple groups will be a problem for you, so it will prevent you from overly limiting your diet.

It sounds like medical attention would be a good idea. In terms of the sleeping, elevating your torso would be a good idea. If a sleeping wedge isn’t enough, you can use a reading bolster. I slept with one for 2.5 months post Botox when my UES was wide open)and I have GERD) and I had no problems. I had a little trouble falling asleep sitting so I also took unisom.
I used this one:
4 Pcs Orthopedic Bed Wedge Pillow Set – Post Surgery, Relaxing, Back & Adjustable Head Support Cushion – Triangle Memory Foam Pillow for Acid Reflux, Sleeping, Reading, Leg Elevation, Snoring (Grey) https://www.amazon.com/dp/B08SKXJ953/ref=cm_sw_r_awdo_MAP6TK32HXY94MYT9H9X
This is the reading wedge I used. Initially I used the whole setup but later I just used the more shallow one that goes under your knees if I’d been drinking.
It wasn’t the easiest thing to get used to so I took a unison to make myself sleep.
Maybe you are talking about this one . I think they are called Heart Palpitations .
Yeah you can literally just go with baking soda. If you want to get fancy/organic about it you can try products like that https://www.amazon.ca/gp/product/B01EMGONAU/ref=ox_sc_saved_title_9?smid=A2BS7YATGL5JW4&psc=1 but its 3 to 4 time more expensive
Samarin is a medication that contains carbonated baking soda, you can get the pure stuff on amazon.

I buy any brand activated charcoal at my local pharmacy. You can also order it online if you'd like. It helps alot with detoxing your stomach and gut. Your body does not break it down and molecules stick to it, so I helps remove any unwanted crap in your GI. Great for hangovers too. I'm not gunna saying it's a cure for problems, but it deffinetly helps me when I can feel my gut rumbling. Using for an upset stomach or after a cheat meal helps alot as well. Amazon charcoal
UpSpring Stomach Settle Drops for Nausea, Gas, Bloating, Morning Sickness and Motion Sickness Relief, 28 Count Individually Wrapped Drops for Tummy with Ginger, Lemon, Spearmint, Honey and B6 https://www.amazon.com/dp/B074MJCC1H/ref=cm_sw_r_cp_api_fab_1OFGFbAFPXBA0 These are pretty good
Hey, the ones I got were "Alliance" brand but I can't find it anymore. It looked like these ones though: https://www.amazon.ca/Perfect-Stix-Sterile-Depressors-Individually/dp/B009EE29F2
The key thing to look for is "Sterile" as you are putting it in your mouth. You don't necessarily need individually wrapped ones as you can probably just put them in a ziploc bag or something.
