Hi, i was wondering if anyone can shed any light on what's happened to me in the last few days. Started feeling really tired and drained on sat nite, so went home and went to bed. Woke up on sunday morning really early, wide awake, but my legs were 'feeling light and floaty' as if they weren't there at all. I know this sounds weird, but i couldn't stand up unaided for any more than 1 min on sunday. I had no energy to do anything. Monday wasn't much better, but could walk a little by myself. Its now tuesday, and after taking 2 days off work am feeling much better - can do most things around the house today without total exhaustion. Legs still feel a little light and 'floaty', as if they're not quite there at times. Not really had this feeling before. It coinsides with my period (which is getting the blame for this) but just curious if anyone else has experienced this or similar, or am i a total freak???
