I take half a pill at night. It is a drug often used for Parkinson's, but I am not being given it for that. The doctor's assistant (who gave it to me) refers to me having a movement disorder. This is the jerking of my leg and sometimes lower back, which occurs mostly when I am at rest, especially in bed at night, but it is more violent than "restless leg syndrome". The Mirapex seems to help this. I am afraid to take enough to completely suppress this symptom, however. When I took a whole one I got constipated and had some pressure in my mid-abdomen, which the doctor said was probably due to taking Mirapex.
However, it does help the leg jerking and spasm and helps me to sleep, so I guess it is a permanent fixture.

I am posting this in case this might help someone with a similar problem. It is listed with a number of bad side effects, but it is also listed as safe for my Porphyria, and anything safe for Porphyria usually has a low incidence of side effects for me, as most of my side effects come from Porphyria.

When this leg starts twisting and jerking on its own, it is painful and makes me cry, wondering when this will finally stop. But Mirapex may help.
