I had this for the first 2 weeks and it nearly drove me insane lol. I constantly felt like i'd been drinking sea water. It did seem to disappear though (or maybe i got used to it? Not sure which lol) But if its still there i dont notice it anymore
I used to get a salty taste when i first started having the choc mint milkshakes, dont know why. It was very annoying but i also found that i didnt taste it as much when if i had more water. Its the only flavour i can stomach now, that and hot choc, mmmm, yum.
