I'm starting week 4 of my keto transition. I can handle the fogginess & rash I've acquired since starting but the nausea is making it really hard to function. I'm sticking pretty close to a 70-20-10 ratio but often find it difficult to consume the number of calories Cronometer suggests for a sedentary (had back surgery after starting transition to keto), 70+ female. There doesn't seem to be any particular food that makes the nausea worse (or better). I take some supplements but I had taken them with no nausea for quite awhile before starting the transition. Is this just something I'm going to have to live with for another 4-5 weeks?
