The symptoms I had were a lot of burning in the throat and upper stomach, bloating, gas, felt like something in the throat, post nasal dripping, dizzy feeling, and low energy. I had symptoms that aligned with GERD, LPR, and IBS. I was on 40mg of Protonix once a day. My doctor wanted to up the dosage as my GERD symptoms were getting worse. I decided to do some research as I knew I didn't want to be on PPI's the rest of my life, let alone up the dosage. I decided that instead of giving more money to the doctor's to take matters into my own hands and get off of them on my own.
In a nutshell, here's the steps I took to get off the PPI's, although not recommended. I cut cold turkey and the first 2-3 weeks were a living hell. Non-stop heartburn plus all the symptoms I described above. I don't remember the exact supplements I was taking, but I tried almost everything that has been tried. I ate a lot of fresh vegetables and fruits and small servings of meat. I ended up losing a bit of weight even though I wasn't even close to being overweight. I started juicing about 1 month after stopping the PPI's and I think this was a big help. I then decided to start taking an H2-blocker (Pepcid Complete) at about the 4 month mark. I now juice every morning and take 2 of the H2-blockers a day. I rarely get heartburn anymore and don't have any side effects. I also drink alkaline water daily. I buy Alkazone drops and put that into filtered tap water. I sleep on a wedge too at night and think that it helps as I don't feel any heartburn anymore through the night or in the morning.
I think that if you taper down it will mitigate some of the more sever rebound side effects. I can't tell you the steps you should take as I am not a health professional, but in your shoes, I would slowly taper away from the PPI's and replace with an H2-blocker as an H2-blocker will allow acid production to break down the food. Once your body is properly breaking down the food and you can digest it, I think this will help with some of the side effects. I believe that some of the side effects are due to your body not getting all the nutrients it needs because it's not producing the acid it needs to break down the foods properly. You may also want to see if you can find a doctor who is willing to try and find the underlying cause of the problem in the first place and then work on fixing that. I can't tell if these steps will help you or not as you may have other health issues that I did not. One thing I do know for certain though is that in order for our bodies to heal, you need to give it the proper nutrition. This is where juicing comes into play as you give your body a boost of phytonutrients that helps heal the body.
I am currently at a little over 6 months of being off PPI's and I would not want to go through that again. This is why it is very important to stick with strict eating habits as it is your diet that creates a lot of these health problems. Once your body gets back on track it is very important to keep it there if you don't want to go back through this again. I can't stress enough how important this is.
I hope this information helps and if you have any more questions let me know. Thanks.
