restless legs syndrome
"Severe restless legs syndrome with Periodic Limb movement for over 45 yrs. Clonazepam worked fine for a long time, then became less effective.  Doctor added Mirapex - it worked BUT: I gained 60 lbs in 3 yrs from obsessive eating, charged lot of money to my credit cards due to obsessive spending (both stated side effects) AND fell asleep without warning, mostly at night (twice while driving), so I tapered off.  Have lost most of the weight, paying off the bills, but need more than clonazepam."
