If you already have an acid surge/discomfort, then I suggest doing it more slowly. In other words, take 10 mg every other day or even every third day. I'm trying to switch from a PPI to an H2 blocker and I started once a week to take an H2 instead of PPI, and then once every 4 days, 3 days, and building up. I don't know yet if I'll succeed but it's so far working to do it slowly.

It may be helpful for you to consult a nutritionist with knowledge in treating healthy eating for gut issues as you taper off the PPI. As you taper off and are totally off, symptoms will return as it did for me. It’s critical to make dietary changes changes to support good gut health.
Here’s what was recommended for me along with some supplements and I no longer have GERD or indigestion:
*Eliminate gluten products - gluten free bread, almond flour crackers, etc. it doesn’t matter if you’re not gluten intolerant and don’t have Celiac disease.
*Reduce sugars - eat low sugar fruit(strawberries, blueberries, raspberries), low sugar vegetables, use only stevia as a sweetener
*Consume fermented foods - Kefir, sauerkraut if you like it, pickles but only from the refrigerated section, kombucha, kimchi.
*Diary - it is the fat that can be difficult to digest. I switched to almond milk, yogurt with A2 protein ( makes it digestible ) or try sheep or goat milk products.
*Eliminate highly processed foods as they have too many chemicals.
Best to you as you go through this. PPI’s can have serious side effects. I was told by my GI to never take again due to side effect.
