I was wondering if anyone else feels this way. On a day to day basis I get a feeling of uneasiness. It's difficult to describe but feels like constant fatigue mixed with a sensation of being about to pass out. I felt this way before treatment and continue to experience this sensation several months into treatment. It's especially bad when I'm out and about. I mentioned this "lightheadedness/brain fog" to my consultant but he's never seemed too concerned about it. I can just about deal with all the other symptoms but this one in particular is by far the most challenging. Whenever I try to explain how I feel it just seems like no understands how debilitating this can be. I try and get a good night's sleep but an hour or so after waking up it feels like I've done a day's exercise in a sauna.
