Norvasc
"At first I got fantastic results.  I have severe Raynaud's and was basically house bound.  It even presented in warm weather.  At first the Norvasc totally removed the symptoms.   They seem to have come back, however, and it is mid-summer.  I also take Ritalin for narcolepsy and I fear that it may be causing some of the symptoms.  I would recommend trying this medicine for Raynaud's.  I take 5 mg per day."
