I don't like Keto either, I get really grumpy on low carb diets but alas that is the beauty of dieting; there are so many different ones and they can all work, so stick with whatever is working for you.

Sounds like you're getting a lot of mileage out of keto so stick with it.

As for Caffeine, yeah, I don't drink it ever. I find if you eat properly and exercise that staying alert and focused isn't really a problem unless you have some underlying condition or are already addicted to caffeine XD
