I only wanted to pop in and say that I started Namenda the end of May. I ramped up to 30mg a day. I noticed improvement at about a week during the ramp up.
I love Namenda.
I have had a hard time with traditional pain meds, so it's like a Godsend to me.
I have been able to stop taking Topomax since I started the Namenda.
It has helped my pain, and REALLY helped the brain fog. Probably took my pain from a constant 6-7 that peaked at 8-9 to a 3-4 peaking at 6. I am pretty level now on pain except for the days when the barometric pressure is FALLING
.... then, I am miserable!
Good luck to you....
