Thanks for the kind words and suggestions. Last night was even worse, sweating and nausea. By running my hands under cold water the nausea and sweating abated. Today I feel a little better, finally got the headache under control but all I want to do is sleep. I make my own lemon water but each time I took a sip the cramping started again. Went to emerg.- dehydrated so a full liter/quart was dripped in. They also dripped in something for the headache which made it worse. Back home I slept about 90 min and headache has finally abated. So far so good with a little food and lemon water, no cramping. Man those were painful.
