If you add sugar/carbonation drops to the bottle for fizz, there will always be sediment. Depending on the yeast used, some sediment can stick solid to bottle and not be disturbed on pouring. But... there will always be sediment.
To have sediment free fizzy bottled beer/cider/wine means going down the forced carbonation route... a route that I'm taking. This is starting to prove expensive for me and it might have just been easier to be careful pouring my beer and advise friends (to whom I give some samples) to do the same.
