There will almost certainly be some reduction (unless soda becomes a Veblen good, which seems unlikely but not impossible) the question is how much the price elasticity is. I found a scientific paper[1] that suggest that under some ideal conditions I am not sure apply to reality a 10% tax means 10% less less consumption. However what do they then consume? A switch from diet cola to juice would be bad from a sugar perspective and a switch to milk would be bad from a caloric perspective. Sparkling water is better from both perspectives but it is worse for your teeth than regular water [2] plain tea seems mixed [3] but realistically would you expect most people to switch to plain tea or tea with tons of sugar?
