Ok, going into Keto i knew that it should take a few days to maybe even a week before the flu officially sets in. But I just started day 2 and I feel awful. I feel like my digestive tract is yelling at me, i feel tired, my heartburn is going crazy (I have had semi chronic heartburn for a few years - hiatal hernia) and just feel really tired. Sometimes I feel chills, sometimes I get warm. Day 1 I know I was WAY under my calorie intake because I was traveling but I didnt really feel bad till today.
Now my anxiety is saying maybe something is wrong. But maybe thats the brain fog convincing me to be stressed out?
It was hard to get my breakfast down without feeling nauseous but I did feel better after I ate for a couple hours. i still feel crummy but im trying to make sure I keep eating and drinking.
