Yes this sounds exactly the kind of fatigue I'm talking about, at the same time my balance becomes worse, although has definately got better, and my sight gets blurry and basically I just feel pretty yuck. But I agree it's so unpredictable, sometimes if I rest for just a short while it lifts or sometimes takes longer. It makes it difficult to plan things, although at present I'm fighting it, which is probably the wrong thing to do, because eventually it catches up with you anyway. It's an ongoing battle with yourself. Love Tracy x <img src="/ubbthreads/images/graemlins/swordfighting.gif" alt="" />
