I've been taking Memantine daily at 20-30mg for the past 6 months now, I'm encountering some peculiar side effects when trying to increase this dosage to the desired 50-60 mg range. The two main side effects I'm experiencing are freezing cold limbs, like my hands and feet cannot tolerate any exposure to cold weather and will literally turn blue! And the other side effect is rapid weight loss, Its so bad that I have literally lost excessive weight which I'm desperately trying to put back on.
I'm not sure if these side effects are common as I've never read of anyone experiencing them when on a similar high dose, anyone have any experience they could share?
