Stomach issues can often be dealt with by looking at your diet, how well you chew your food,
exercising, meditating, not going to bed too soon after
eating. Some people have some of these problems because these meds can interfere with magnesium absorption, so trying a magnesium supplement -- most do well on the citrate or taureate form -- before going to bed can help. Usually, you would take magnesium with a meal, but for these symptoms, taking it at bedtime can help some.
