I did my first flush last night and was somewhat successful. During the night I woke up sweating, shivering, dizzy and needing a toilet bad. This only got worse until I was able to expel the sludge from my body at that time (I have read that other people have thrown up). Finally I went back to bed, however I had to get up early this morning and am now at work. I really could've used the extra sleep today and my head is throbbing....is there anything I should or shouldn't take for this horrible headache?! I am ready to grab the bottle of Excedrin any minute!
