HI, I m taking Namenda XR and have just finished ramping up to full dose of 28 mg. during the ramp up, I immediately had severe had stomach pain-- so my GP stopped my Mobic and had me do every other day of the Namenda XR. So it s been in my system to some degree for almost 8 weeks... But I am now taking it daily and feel dizzy, nauseated, and tired. Here s my question: would taking it every other day have any efficacy on the tiny white (as in dead, I think) blood vessels found on MRI? Also, since the XR is so flaming unaffordable I will be taking the not XR lower dosage pills, twice a day. Thoughts?
