I normally have a double-strength soy latte with one sugar each workday around mid-morning. That obviously has to stop. Today I had a double-espresso instead. It was surprisingly enjoyable, though not as indulgent as my usual. My backup option would be a sugar-free red bull (or similar).

Any other tips for a caffeine hit without the carbs?

Now I'm having a very large cup of instant coffee with unsweetened almond milk daily. Sometimes two. No artificial sweeteners either. Tastes pretty good.

Last time I had a soy latte with no sugar from a cafe I could tell right away that the soy milk was not the "unsweetened" type.
