Eleven weeks on reta. Appetite down, food noise quieter, all expected. The odd one: carbonation tastes like static and old pennies. I used to have two cans of fizzy water after dinner; now one sip and my mouth closes the tab. No nausea, no reflux—just a corrupted flavor file.
In my side-effect log it's the only entry that isn't appetite-adjacent. Mildly annoying, mildly useful, since my 9pm soda habit was mostly ritual.
Did your taste change in one narrow category like this, or was it broader?
Same—sparkling water went from my 8pm treat to tasting like licking a battery. Weirdly, cold was worse for me.
I started pouring it in a mug and letting it sit 10 min; half the fizz gone, penny taste mostly gone. Tracked it in my notes app: static 4/5 weeks 9–13, faded to 1/5 by week 16.
Question: does it hit all fizzy stuff or just plain? Cola was flat but still sweet for me; plain was the worst.
My snack drawer now has lemon packets to mask it when I want bubbles. Kids think I’m nuts.
I’m back after a regain, so I’m collecting weird side quests too. Not carbonation exactly, but coffee went the same way for me — smelled right, tasted like burnt paper.
What helped was logging brand, temp, and container. Canned fizzy water = static/pennies; the same stuff from a glass bottle or poured over ice in a ceramic mug is way less offensive. Plain cold
Honestly, i’ve been logging taste weirdness too, and mine seems timing-dependent. First sip of anything fizzy is normal, then around 10–15 seconds I get that penny/static thing, and it fades by a minute.
Ice-cold is worse; room-temp flat water is totally fine. Does yours hit instantly or build?
Also, have you tested other carbonated things—soda, kombucha, those fizzy probiotic drinks—or just plain sparkling water? I’m curious if it’s the bubbles themselves or something about the specific drink.
Not scary, just a strange file corruption I’d like to map.
I run a cafe, so I’m tasting fizzy drinks all day, and that penny-static thing hit me too—only with bubbles. Flat water with lemon? Totally normal. Sparkling anything, even the fancy stuff, tastes like I licked a battery.
I added a little “flat vs. fizzy” note in my log and it made the pattern obvious. Weird question: if you let a can go completely flat, does the old-penny taste stay or disappear?
Because for me it’s the carbonation itself, not the flavor.
Between school pickup and nugget negotiations, my 8pm fizz was my only adult ritual. Mine didn’t just hit sparkling water—Diet Coke tasted like a rusty coin, and Pop Rocks were straight-up pennies, so those left the snack drawer fast.
What helped: cold flat water with a splash of cranberry and lime in a wine glass. Still feels like a treat, zero static.
Curious—does yours wreck anything else, like mint gum or citrus? I’m trying to figure out if it’s the bubbles, the cans, or just cold driks in general.
