Set yourself up for success, don't even leave going back for a day or week as an option. Yes, go see an addiction therapist, I find psychiatrists are more prone to prescribing meds and therapists do talk therapy or CBT. It won't be easy, no matter what, but you are stronger than you think you are. Going backup in dosage or going back to the clinic after the taper is done should be put out of your mind. If you leave that as an option, chances are your brain will make the symptoms worse, so it can get what it wants. No joke, I used to go into methadone withdrawal, physical symptoms, when I knew I had enough in my body, but didn't have any for the next couple days. The brain is that powerful about this. Slow down the taper, if you are concerned, but don't go up in dose or back to the clinic.
