Mate, its been 8 days since I stopped taking 300mg of codeine per day for 8 years.
I feel very good, very happy, positive about the future, all I need is a little more energy
The first 4 - 5 days are utter HELL. Its like the devil cutting off the top of your head and doing a massive satanic dump that fills your body with pure toxic withdrawal and unhappiness. Good thing is, you sweat and crap that devil turd out and after a week or so you start to feel happy again!
Seriously though, the first 4 - 5 days suck, then you start to feel better, after a week you will feel so much better that you will be real glad you done it
Good luck mate,
