I'm on day 7 and finding myself really shaky. I don't think it's lack of calories or anxiety but I do have suspicions that it could be something with my thyroid. I don't have a diagnosed thyroid issue but I am on "watch" for it (nodules + strong family history). I'm often cold (and can't adjust to temperature changes at all), lose tons of hair, struggle to lose weight, etc. Anyone else have this or have any insight? I was absolutely not expecting to feel worse on Whole30 (I cut out caffeine as well...) so I'm frustrated. Thank you!
