Sorry for posting all these threads; I seem to suffer from all the side effects in the world! I'm going to ask my CDC today but since yesterday I seem to be getting headaches. I'm drinking 4.5 litres of water so I can't be dehydrated. I'm also slightly stressed at the moment (but I am in general and never really get headaches). Just wondering why I'm getting these headaches. I never got any headaches even during the first three days. I was wondering if it could be something to do with my blood pressure?
