just to let you know, i past 11 weeks have lost over 3 stones and to be honest, i cant do the whole plain water drinking part, so i use the sunshine powder stff you can get from CDC which is great helps you get through tons of water, but to be honest i drink a lot or zero coke (i know its bad for you!) and water fruit shoots apple flavour, i havent seen anyone mention the fruit shoots before but the apple flavour has malic acid and not citric acid like the other 2 flavours and i have bout 8 of those in a day (a lot i know) and to date i have not come out of ketosis! so dont fret if you dont think your getting enough plain water just make sure you get it in somehow!
