This is always a problem when such type of medications are stopped cold
turkey after a prolonged use for many years.Idelly such type of medications are withdrawn slowly.
You can try doing it sme now.
You can restart your oxodone again with a lesser dose of 35 mg daily and then start withdrawing 5 mg every month.
This way your body would adjust to a slightly lower dose every month without creating much problem to you.
No doubt,it is going o take few months but you shall be able to come out of withdrawl symptoms easily and without any stress
I hope it helps.
