Just to give an update. Mannitol is proving to be amazing for me still. After my initial day of huge improvememt I have plodded along feeling stronger and mentally sharper when 2 days ago I had a day of feeling very sharp mentally and the next day my body felt 'normal' again! My right hand is even more dexterous and my hands now wwork as a pair, r hand just automatically doing its thing and swing is automatic whereas just week ago i had to encourage movement. This big improvement is like last one following of day of improved mental ability.
