| I only drink water, and the occational juice when I've taken too much insulin (like now).
But sometimes I do get sick of water, so I have a little bit of lemon or lime in it. It gives you a little taste and can get you through times when you're tired of the plain water.
You should also only take insulin for what you know you will eat/drink, find your basal dose and then always inject when eating. It works very well for me and you get good control.
You're the best person to motivate yourself, all of us can help. but you're the one that have to take the wheel.
My personal motivation is that diabetes isn't going to get me, and I want to live for a very long time so I can see my son grow up. |
