Home remedies for heartburn never really worked for me. I tried everything - mustard, brown sugar, milk (and avoiding milk!), apple cider vinegar, apples... not all together, of course. :p Last pregnancy I ended up taking antacids, which I have since learned you shouldn't do due to aluminum - oops! - and, well, that didn't really work either.
But... last night I'm pretty sure I hypnotised the pain away! I've been doing Hypnobabies for a few weeks, so I just kept visualising my throat being washed in white light (which is how they tell you to visualise anaesthesia), and "breathed" the pain away... yes, it sounds totally hippie-dippy, but it worked! I did have to repeat the process every time I turned over, though... but I fell asleep pretty quickly and felt fine this morning. Cool, huh? :)
Also, I'm pretty sure mine is aggravated by stress. I locked my keys in my car last night, and had heartburn all evening.
Right, gotta go see my midwife!
