I Just Found Out I Am A Diabetic - Tho'

I just found out I am a diabetic - tho' what level I am at I can't tell you because I have not met with my doctor yet but I figure knowing what to drink and what to eat is a good place for me to start for any level. My real concern right now is staying hydrated. I have struggled with this one all my life but now I can't have the sugary drinks I am used to. I've been watering them down (1/4 sugary drink and 3/4 water) but I since I cannot do this any more what can you suggest?
