Hi
I cold turkied Valium 18months ago. (Due to very bad advice from my GP)
So you are very lucky your G.P. Understands how important tapering off Valium is.
I was only taking 2-4mg twice a week, but eventually was developing tolerance withdrawal symptoms in between doses. (I didn't know what withdrawal was at the time. I just thought my anxiety was getting worse. Never for a minute thought it was the drug)
About 2weeks after I stopped taking it, I developed terrible neck and head muscle tightness head shooting pains. (That no painkillers helped) Also tinnitus, worsening IBS, tremors, sweats, worsening anxiety, tearfulness, anger, memory loss, loss off appetite, and lots more. This went on for two months. My GP couldn't find a cause. I googled my symptoms and hey presto ...withdrawal came up!
I too was really worried, because there are horror stories out there and no one can tell you how long it will take for the withdrawals to stop. I was very scared I would never heal.
But please be assured everyone does..
Taking Valium basically stops your body from producing its own relaxing chemicals, and when you stop, your body's anxiety has no counterbalance...until it starts to reproduce it again. This might take a couple of months.
Every person is different in their withdrawals and their timescale to heal. But. You will heal. Whilst the symptoms are distressing, they will ease and eventually stop.
So, the answer to your question is. It is withdrawal. Not your anxiety. You will come to realise just this when you have healed .
I cold turkeyed, so my withdrawal was extreme. You are tapering, so any withdrawals will be gentle, and from what I have read from OP experiences they ease after a few days from each lowered dose.
