sign that betaine hcl isn't working?

I read on many posts the dramatic difference taking HCL made for people with digestive disorders. I went a week with acid reflux and bloating after eating recently and was good for about 3 days, only for it to come back after eating an orange (yet I can handle apples and bananas...is indigestion a sign of citris allergy? I could always handle it before...perhaps my system hadn't prepared enough for citris since it just started feeling healed? or perhaps could I have TOO MUCH acid and the orange aggrivated it?
anyways, very aggrivated that I hadn't gotten better (I was so dissapointed when myn symptoms returned!) and desperate to ease the bloating and reflux I was feeling in my throat I stopped by the vitamin shopand bought some beatine HCL. I took it with a meal including protein (almonds and garbanzo beans were the protein as Im vegetarian) and I detected NO change at all. It didn't burn my stomach, but it didn't help anything, ether. should I take this as fact that I don't need this supplement?
I do have Acne as well and am now starting to think its candida related. I am about to pick up a colon/ parasite cleanse and after that will be doing a liver flush. will this help with the candida or should I get something that treats the candida as well?
any help is so appreciated!
