I am newly diagnosed with Early Alzheimer's and have been put on Aricept. Been taking the low dose for about 3-4 weeks now. I am having trouble with very painful leg cramps when lying in bed at night. Tensing or flexing the leg makes it far, far worse and I try to lie still until it goes away and I get off to sleep. I think my circulation has been affected too as my feet are like ice. I use a hot water bottle which helps a lot. Also, I have balance problems when I get up, and mild nausea. I've noticed a dull headache which lasts all day as well. Paracetamol helps. The memory clinic intend to double the dose in a few weeks time, which worries me. Can anybody tell me if I can hope to be free of these unpleasant symptoms eventually? Thank you.
