Hey Heaven. :) I just did a basic skim of what you were discussing and I wanted to recommend orange juice to you!
I think you were saying you struggle with needing energy in the morning, correct? Well, caffeine definitely is not the solution. If you're looking for immediate energy, not energy that will happen in a few hours and then ZAP you of energy later, drink ORANGE JUICE
Having vitamin c (really best from the fruit itself if you can) first thing will give you energy for the rest of the morning/afternoon. :) If you really like bubbles because of soda, you could always find a sugar free/low carb soda water/club soda and just mix that with the OJ!
