Is long-term use of Emanera safe and what to eliminate from the diet for the duration of treatment?

After the end of the eradication of helicobacter pyroli ( 14 days pyrely 4x3 treatment, Emanera 2x40 mg, Enterol) I have to use 1x40 mg on an empty stomach for two more months, and then go down to Emanera 1x20 mg for more than a month. I do not have and did not have any problems with the stomach and duodenum, ulcers, no najarek, inflamed before the treatment. Gastroscopy and colonoscopy fully correct. The bacterium was detected by accident (not due to any symptoms) and only because it was ordered to be eradicated. The question is whether such a long use of Emanera will not adversely affect the body? In addition to alcohol and coffee, should I eliminate something else from my diet? Citrus? Silage? is it that I take drugs that inhibit the secretion of stomach acid does not affect the digestion and functioning of the digestive system? I am worried about this whole treatment, because I would not like to lead to the appearance of problems with the stomach and digestive system ( which I did not have before) by the use of strong drugs for such a long time. Best regards.
