Hi Allan My husband 76/11 takes the same meds as Barb. He has high B.P. Some days as high as 210/105. I don't know if the BP is the problem or not--they're all so doggone different are they! However he can be in 200s in the morning and 136 or so in the evening so maybe the medication DOES cause the BP to fluctuate. Mel does have periods of freezing-I understand that comes after years on medication. His toes seem to stick to the floor-if I'm not around he will get tired and sit down rather hard. He does fall a lot. I've read a lot on the list about different Parkies having the postural hypotension where BP drops when they stand up. Trick is to sit up slowly - rest a minute-then rise to the feet. Barb probably does that so I don't know if this has been any help or not KEEP THE FAITH!!!!!
