Hello everyone. I have been taking mannitol for the past 4 weeks and have noticed some improvement. i have definitely been sleeping better. i wanted to try cutting back on C/L to see what happens. Presently I am taking 1/2 azilect in the morning with also 1/2 C/L & 1/2 C/L extended release every 4 hours. I am going to cut out the regular sineret C/L 1/2 tablet and see how that goes today. I would appreciate any input and would love feedback from those taking mannitol. I also take NAC 600 mg 2x daily.
