It mimics soda in that it triggers the same release as I get from chugging soda. It's a particular "refreshing" feeling that makes my eyes water. I suspect for soda it was the sugar addiction that gave me the release, but because both are carbonated it tricks my brain. Or maybe it's the carbonation alone that triggers it.
100%. I especially get a craving for coke after having carbs or fried foods. I recently tried Topo and have fallen in love with it since it fills that craving. But make no mistake, other sparkling waters to me taste like shit. Topo just hits different.
