Cathy, when my dad stopped getting a Sinimet before bedtime, it helped him sleep through the night. Also he was always warm and my mother gets too cold from the air conditioning if it is set less than about 75 degrees F. A fan kept dad cooler at night while the A/C could be set at a higher temp. This helped him get to sleep and stay asleep. I hope this is of some help. [log in to unmask]
