I hate that KETO flu I get when I'm trying to get back into ketosis after too long a time out. This has surprisingly helped a lot. I had some left from last time and I realized how great it's working. I also just have an overall feel of wellbeing, energy my joints are already feeling less inflamed on day 3. Usually it takes a week or 2 to start feeling good. I noticed my hunger was not as great, also. That could be due to the bullet coffee too. So I was already reaching to order another bottle on day 2 to make sure I have some when I run out.
