I should make sure you understand the dose of clonidine it is .1mg, that's point one mg, (one tenth of a mg)
I have restless leg and tried all the different RL drugs (Requip etc...) and none worked. I was finally given a prescription drug to try called clonidine which is actually a blood pressure drug that has been around for a long time. NOTE it is CLONIDINE NOT klonipine.
I later found out that this same drug is helpful when going through withdrawal. It is a prescription med but your GP or family doc might be willing to help you out by prescribing this.
The dosage I take for my restless leg is .1 mg but my doc writes the prescription for .2 mg and I break them in half.
You might also want to take a look at uspainfoundation.org and see if they have any suggestions that can help.
Good Luck and keep us posted on how it goes.
There is a product by Hyland's (Restful Legs?) that is said to be useful with this problem. Wearing yourself out during the day has also been claimed to work because by the time you fall into bed, you're too tired NOT to fall asleep, legs or not. I wish I could help more but everything I know about this I learned from others. I, myself, have never experienced restless legs so I'm afraid I can't give you any first-hand information.
