I’m a 46 year old female. I woke up last night after being asleep for about an hour feeling very nauseous, weak and sweating. I went into the bathroom and had to lay on the floor as I was so weak. I could feel the blood draining from me and after about 5 minutes I felt a little bit better and went back into my bed. I still felt really unwell like I have never felt before. It took me a long time to be able to go to sleep again and I kept waking up feeling a bit unwell
