I'm 35 years male, heights 175 cm & 75 kg i, was a heroine addict for past 2& half years (smoking heroine) now i'm sober for 3 months? I took addnok 2 mg quarter a tablet morning and evening for 2 months, now i'm on tramadol 100 mg, notipam m and large 2 mg i've stopped taking addnok now, doctor when will I get rid of this withdrawal? It's already 3 months i'm off from heroine, I still I get this muscle cramps on my stomach, biceps and my back muscle above hip, and i'm scared of this heroine now. Is tramadol addictive? Is there withdrawal symptoms if you stop taking tramadol?
