Doc prescribed Donnatel. He recommended to take "As needed". I'm a SAHM and when I'm at home I'm pretty much symptom free maybe leaning toward constipation. When I go to the grocery store, shopping, out to dinner, etc..it's a different story. I feel it coming on like a panic attack, I get shakey and sweaty and I have to find a bathroom right away. This drug makes me loopy so I really don't want to take it all the time, but if I did, would these side effects subside? So in my case, what would be the best way to take the meds? An hour before I went out? Once a day? Any suggestions or ideas are appreciated.
