It is! 
There are some really high strength acv tablets in Holland and Barrett, also Boots. They are pricey But often those shops have supplements on offer. They're in a light bright apple green box. They are really good for balancing the acidity in the body.
Bottled vinegar is cheaper, but if you can afford the tablets, they are super easy, and super effective. And no taste!
If you give up stimulants (tea,coffee,cigs,alcohol), limit your sugar, and ignore spices, add acv and some probiotics, you'll be amazed at how much more comfortable you'll feel.
Personally, I can't do cooked tomatoes in the evening. Oh, also, don't eat late in the evening, if you get it when you lie down at night! Eat earlier, or if you can't, you may find it better to sleep propped up.
But basically as soon as you get more alkaline you'll be fine.
