You may think you’re going to die, but most of the withdrawal
symptoms are just very uncomfortable. Opiate withdrawal
symptoms usually start 12-24 hours after your last dose. But, the timing of withdrawal symptoms depends upon the drug taken, length of time you’ve been taking it, and how you react to medications. The physical withdrawals usually last 3-7 days, with days 3 and 4 being the worst. Once again, this is all dependent on the person. You can expect these symptoms.
