I dont' think it has anthing to do with acid - i suspect that "acid in my throat" refers to heartburn - he's written a lot of songs about the period he was heavily into methamphetamine, when you haven't eaten for days, you can get some terrible heartburn. "wringing my hands, grinding my teeth" "the songs that keep me up at night" "Thank god for small favors in high doses" - this all sounds like a come-down to me.
