Type 2 Thirsty - Drinks During the Day

It is important to drink water.....but could i just ask coffee,tea,squash,sparkling water etc how many types of drink and how much / how many drinks throughout the day (if fasting or trying to stick to a low carb format).
Some drinks have sweeteners even sparkling water lemon and lime type drinks. Tap water with squash just
trying to get an idea of what others might do....i tend to do coffee in the morning but given advice that its ok
to put cream in it...i do that now on the days i try to fast.
But how many cups of tea a day is it best to try to switch to having it black - no milk at all can you have tea
whilst fasting? Cold drinks - i know water is fine and encourage but is it ok to have say sparkling water and
some no added sugar squash or tap water and squash. I am sure others might have other drinks hot chocolate,
lemonade etc - I switched to skimmed milk very few if any eggs -years ago when it was suggested not good for you now i am having to retrain my brain and change my shopping list whilst trying to fo Low Carb and Fast.
Need a cuppa now i have moved up to semi skimmed milk to have with it....trying to make changes that i can stick to.

Thank you all - you have given me some ideas and a guide to tackle liquidity - i am partial to a glass of red or even white wine on the very special occasion.....but it was the cuppa tea that i need most days - i think i can cope now knowing i can have that and more if i take care. Rooibos,green tea seem popular - have to say today i found a liquorice ginger and turmeric teabag item at Sainsburys. I think it will be like Marmite love it or hate it type tea - will probably be straight back to ordinary but i saw the turmeric and thought thats suppose to be good for you. Once again many thanks for telling me your favourites and how many cups/mugs a day.
