Ok, I know this is going to sound bizarre but...

I am doing the pre op diet (mostly protein shakes) and I have a constant sweet taste in my mouth. It is almost like an artifical sweetner (which I do not use).

Any one else experience this or am I just the odd one??

i think there is a sweetener in the drink,is it the sugarfree one?

The weird thing is that I drink water to rinse this out and it still comes back. At first is was just now and then, now it is constantly there. It's driving me nuts and completely leaves me not wanting to drink anything.

check the ingredients in shake??? are you making your own drinks> or buying pre made

I get a sweet taste in my mouth with splenda (sucralose).

If you have the equipment, check your blood glucose level when this happens. Mine goes up with splenda - even though "they" swear that's not supposed to happen.

I would rather have a sweet taste. I am also on the pre-op diet and I have a salt taste in my mouth that I can't get rid of. It drives me crazy and I still have 10 more days on this diet. Had it since the first day. It is always there and at certain times it gets worse. I was never really a salt eater plus I have HBP so I stay away from a lot of salt. Can't figure this one out.

It might be ketosis due to your low carb intake. I had a metallic taste in my mouth, but others describe it as a fruity or sweet taste.
