I went through a similar phase at around 2 months of starting keto. It wasn’t as painful to me as it sounds it is to you and I was able to grunt through it. I do remember thinking that it was all the extra cheese and meat I was consuming and also the slightly lower quantity of veggies but I don’t know for sure. In addition to the cramps and bloating I got constipated. I also got lethargic at this time and seemed to lose that “walking on sunshine” feeling of the first few weeks. It felt like a delayed keto flu.
Eventually my stomach settled but I couldn’t tell you exactly what I did. I was always listening to the podcasts and adapting my keto regimen accordingly: upping salt, fasting, drinking lemon juice, taking a multivitamin, stopping counting calories and eating more fat. After a while the stomach discomfort just passed and I didn’t even notice.
I was advised here on the forums that it could be my electrolytes. So I worked on those. It’s really nice to know that cause of a problem but sometimes you just gotta throw everything at it and hope it irons out - that’s what I did. And apparently it worked and I think that’s probably when I got fat adapted.
The way I looked at it was - my body is rebelling against carb withdrawal. And the only hard work was eating more fat.
All the best to you!
