I really really struggle to drink enough, even to the point of not drinking for upto 2 days (that was last week, no food or drink for 48 hrs) and not yesterday either (but ate thick soup). (recovering anorexic, please don't judge)
Today I have woken with mild, regular pains in my lower abdomen, with some pains in my arm.
What does long-term dehydration do? Could I have done some harm?
