We all have things we wish we didn't do in taking care of ourselves. Including not getting enough sleep, too much caffeine, not enough water, consuming too much sugar. Taking care of yourself today means a better tomorrow and for the long term. The sooner you eat better, drink enough water, and getting enough sleep, the better. Delaying this, with the health issues you have now will only compound later on. One step at a time is closer to where you need to be. Even with one step, you will feel the progress and reap the longer term benefits.
