There is ALOT of help, support and advice out there pal.
Dont panic, is my first bit of advice.
Head on down to The Dark Side section of the forum and you will find great support there.
There are alot of options, from Kratom (fantastic for opiate w/d's...absolutely amazing. I had next to no w/d's from poppy pods thanks to kratom - its a tree that grows in SE asia, you consume the leaves. It's legal. It's not an opiate, but an opioid - meaning it essentially acts on the same neurotransmitters as opiates, but isn't a derivative of the poppy) to Suboxone, to a tapering program or utilizing any other tools in the arsenal of withdrawal weapons.
You are not alone
You aint got nothing to fear.
As long as you truly have the drive/will/desire to give up, then maintain that healthy attitude and find help within these forums, fromyour doctor, from friends.
