Well done getting off the codeine! That's greatThe Codiene detox was easy didn’t feel any different. It’s the diazepam is the one. I dropped down from 80mg to 40 mg yesterday woke up this morning with that start of a withdrawal feeling. Really it’s nothing but I’m paranoid about it. In past Diazepam detoxes I had seizures, uncontrollable shazing, hallucinations. Real bad stuff I remember one about self combustion I was just laying there my temperature going up and up and resigned that I would burst in flame. I feel like I can’t tolerate the feeling of withdrawals.
Drug free I always feel full of energy fed up with feeling lethargic too.
Someone else asked I’ve dropped the Pregabalin from 75mg to 50mg. I have.
As I’ve mentioned recently I feel like I’m on too many different drugs. If I was on 200mg of diazepam and nothing else I reckon I could self taper that easily.

Yes the diaz is going to be a bit more of an issue....remember to take it slowly with the diazepam otherwise you'll keep taking one step forward, two steps back.
If you can, sit at 40mg for a week or two and see how you feel.
Try to keep in mind that when you're coming off a drug, there always has to be some level of discomfort. It's never going to be completely easy, and feel comfortable and lovely. By definition it HAS to be difficult at times. So resist the temptation to increase your doses back up as much as you can, and take it one moment at a time.
