倒不一定是胃炎或者溃疡才有反酸的症状。
大多数反酸是因为食道那里压力减小，贲门在不该开的时候开了，所以酸液倒流。奥美拉唑(omeprazole)的胃肠副作用很常见，如果你觉得很难以忍受，那就不要用了。
如果确信不是胃酸引起的，还是去换个医生，查查究竟是什么原因吧，别耽误了。

如果想把头垫高，防止胃酸倒流，正确的方法是把书，或者砖头垫在头的一端的床脚，而不是枕头底下。不然胃酸窝在胃里面反而让情况更遭。
我LG胃反酸导致喉咙痛，给折磨了很多年了，试了各种药，各种life style modification 都没啥用，看了几次医生都帮助不大。不过他不久前自己给自己治好了。
大胆和你说一下，不一定和你的情况一样，仅供参考。
他的理论是他不是胃酸过多，而是胃酶不足。所以导致实物不能完全消化，积在胃里，逐渐build up pressure, 然后史得贲门敞开，胃酸倒流。他用的是在vitamin shoppe买的 multi-enzyme, 里面最主要得成分是 betaine HCl, pancreatin. 刚开始的时候我觉得他的想法很crazy,因为我在学校，教科书里学的都是抑制胃酸，尽量避免酸性食物，从来没见过用消化酶治疗胃反酸的，听起来很counterintuitive。但是他用了这个multi-enzyme之后几天咽喉症状就全好了，现在他如果吃多了，就吃一粒这个enzyme,防止反酸。

interesting!
听你提到吗叮啉，去查了一下。因为印象中这个药再美国好象不大用的。这个药的作用是加快胃肠蠕动，从而加快胃排空。不过一般在这边，这个不是治疗反酸的办法。
吗叮啉再美国酶通过FDA批准
如果你有兴趣，看这段：里面说的 domperidone 就是吗叮啉。

Janssen Pharmaceutical has brought domperidone before the FDA several times in the last two decades, with the most recent effort in the 1990s. Numerous U.S. clinical drug trials have demonstrated its safety and efficacy in dealing with gastroparesis symptoms, but the FDA turned down Janssen's application for domperidone, even though the FDA's division of gastrointestinal drugs had approved domperidone.^[8]

In June 2004, the United States' main regulation agency, the Food and Drug Administration (FDA), issued a letter warning women not to take domperidone, citing unknown risks to parents and infants, and warned pharmacies that domestic sale was illegal, and that import shipments from other countries would be searched and seized. Domperidone is excreted in breast milk, and no studies on its effects on breastfeeding infants have been reported in the literature. Individual incidents of problems with the drug include cardiac arrest and arrhythmia, complications with other medications, as well as complications with improper intravenous use^[6]. A recent paper suggests there may be increased risk of seizures to neonates of mothers taking oral domperidone^[9].

这个在中国挺常用的吗？以后有机会要去查查中国的clinical 文献。

睡觉时张口我就不懂怎么解决了，试试侧睡呢？
如果我平躺睡，有时也会张口。

他本来吃的就很少的，多餐少食，忌酸性食物，饭后不马上躺下，这些都试过的。
不过他现在基本上好了，不用经常吃药也不会有问题了。
