I must disclose I do not get Ms fatigue. I have thus often asked this question to others. The best description I've heard is to start with you feel like you're walking normally you then feel like you're walking through water up to your neck the water then gets thicker like honey and eventually you feel like you're walking through rapidly setting concrete. Would be interesting to hear others views as it's something I may suffer in future.

Thats a good description. I feel like I have run a marathon while im actually just sitting down. I feel the need to go back to sleep for a couple of hours even though i dont need to. Its like..your body and brain are divided. You want to do something but you cant because you have zero energy and you can't moyivate yourself no matter what. I know when im exhausted that I cannot force myself to do anything. Its a cruel condition but please be kind to yourself.
