Cold turkey or rapid benzo tapers are rough. I feel for you. I had really bad insomnia when I tried to quit opiates cold turkey...like I swear I actually went 6 days straight with NO sleep and even when I started sleeping again it was only for short durations and all broken. I was exhausted and at one point I thought I would die. Ambien helped a little but really not much. Trazadone gave me a fast heart rate. Kava root helped a bit as did Valerian root capsules. I also found a bedtime ritual of a warm bath, sleepy time tea, and lavender oil on my pillow helped some.
A few months after I did the cold turkey I developed something called adrenal fatigue. It is likely that this was caused by the opiates long term as well as stress in my life and the 60 day detox hell didn't help things any. Anyhow, it took me months to figure out how to treat it and I am doing really good with that now. Key symptoms are extreme fatigue and difficulty sleeping. I started taking adrenal support herbs which contain Rodiola and Ashwaganda (and a few others) and it took 6 weeks but boy did they help! I also got great relief from doing restorative yoga. Within 4 days of starting the yoga, I was sleeping 5-6 hour stretches! There is a book called "Yoga As Medicine" that details what to do. Totally worth the money. The positions for insomnia are called "legs up the wall," "downward facing dog" and "headstand." You can Google them. Also try meditation. REALLY hard to do in the beginning but it will help with the sleep and anxiety.
I am doing OK. Working actually helps. It forces me to get up and move and when I am taking care of others I focus less on my own suffering. Mornings are the worst. Hard to get up some days but even that has been better the past few days. The worst part of the day is when it is coming time for the next dose. I have been trying to stretch the dosing interval too.
As for the tapering, I plan to try to reduce one pill at each dose (so 2 pills or 4mg) at each drop time. I will try for a drop every 2-5 days but know I need to listen to my body. As the taper progresses, I will probably need to reduce the amount of milligrams dropped. If it has been 5 days and I still feel crappy, I will hold until I feel better. So far, I have been able to drop every 2-3 days. I guess I am not in a rush. It took me 6 years to get here. It may take me 6 months to get off and then 18 more months for my brain to heal up.
You are welcome to post your progress here on my thread. I kinda feel like Roaddoggy when it comes to threads. Quitting takes support so let's help each other out. As far as you quitting the pain pills, only you will know when you are ready and it really does come down to that. You have to want to quit AND be ready to really do it. With your body still hurting from the Valium detox, it might be best to wait until you are feeling better to start the next detox.
Hang in there!
