If you are dizzy be careful when standing up and be sure to wait a second before walking. I have a $50,000 ankle because I didn't do this with a med that was lowering my blood pressure and I fell and tore a bunch of things. If that continues you need to check your blood pressure and make sure the clonidine isn't making it too low.

I've heard this can help. I've never tried it myself; I have low blood pressure so can't take anything that lowers it further.
