Zanaflex and urination

Given Zanaflex after 6 back surgeries. Dosage take 2 tabs (4mg) 4 times a day. Total dosage 24hrs (8mg x 4 = 32mg.) This seems high to me. What happens is my stomach does not digest food, mobility slows way down; can not urinate, pass gas. I am a 52 female, with spinal problems. I also have HTN, and when I miss a dose to drive, my face is flushed bright red, B/P soars in the 200's. I can not move my bowels up to 10 days. I am now off this medicine and yes, I hurt, but, once in awhile I will take 1/2 tab. Anyone else experience such bowel, urination problems? And, yes, the HTN? I am now on the generic. This is the medicine from hell. I feel better with a lowered dose. Please help me with your comments. by kwncln
