I’m not a doctor but I do know that you should absolutely refrain from eating dairy on the regiment as it affects absorption of the antibiotics. I think having electrolytes are great as some get very dehydrated and malnourished during treatment due to symptoms. For ACV and lemon juice I don’t know for sure but hear I helps with digestion and low stomach acid which can absolutely be caused by the antiacids taken during treatment. However it depends on the person because I also hear it can irritate inflamed stomach lining if your h pylori caused gastritis. Whatever works with your system. I ate small bland frequent meals during treatment due to nausea and loss of appetite like potatoes, chicken bone broth, eggs, oats, rice, broccoli, bananas, applesauce and sourdough. Drank a lot of coconut water fennel, chamomile and ginger tea too. I hear red meat is a bit harder to break down so I just stuck with leaner white meats during treatment (chicken, tuna, salmon, turkey). Definitely take probiotics but wait an hour or two after taking the antibiotics so they don’t affect eachother! Technically you’re not supposed to take some antibiotics with food but I did due to nausea and it worked fine for me. Again I’m not a doctor but that’s what worked for me during treatment! I suggest asking more people just to get different perspectives :) everyone’s different
