29 weeks heartburn

Kasha

I honestly can't deal with this heartburn any longer, its keeping me up at night, none of these heartburn tables are helping, ive had milk/yoghurs you name it, nothing helps, been up at 3;30 am vomiting yellow stuff up and couldn't get back to sleep baring in mind i had to go work, please someone tell me what else can i take or do to at least get rid of it for a few hours
