Seconded, don't ve too hard on yourself buddy. You're in the home stretch right now. You've gotta be able to take pride and find joy in what you've accomplished to motivate you in the hard times.
If you find this is a hurdle that is too difficult to get over easily, I would advise thinking about something like Gabapentin (Neurontin).
Gabapentin was an essential part of my getting pff Heroin. I've already discussed this in another thread just a minute ago. I'm a major proponent of "using everything available to you" when trying to quit Opioids, this means therapy, medication, exercise, spirituality... everything.
Anyway, for many, myself included, Gabapentin is the magic bullet for RLS. By the way, RLS is my most dreaded symptom too. It's the worst.
