I was taking a low dose of Mirtazapine to sleep for 2 weeks. I stopped it cold-turkey (I was down to about 3mg) and, after a few days, became very restless, felt a disconcerting stiffness in my face/jaw, and overadrenalized basically. My mind feels blank/locked and it can be hard to think clearly.. I've had similar cognitive symptoms when a stimulant dose is too high.
6 weeks later, I've tried:
1. Antihistamines (Doxylamine, Cyproheptadine), which fix the inner restlessness, but wire me more. Reinstating the Mirtazapine just wires me.
2. clonidine, which helps the restlessness too, but makes me depressed/anxious.
3. Benzos, which I can't take due to paradoxical reactions.
4. Propranolol, which helps slightly, but makes me feel sick and hypoglycemic.
5. Opiates -- codeine, and a low-dose of some buprenorphine I was saving for depression -- which are great for mood and everything, but actually stimulate me too, rather than sedate. The buprenorphine, which I only took once, made me vomit heavily and I grew more irritable eventually .. so if that's a sign the dose was simply too high to start with (0.25mg of a sublingual strip), I would try it again.
I've been to emergency twice, because I was growing suicidal, and told there was nothing they could do; I couldn't get to see a psychiatrist or neurologist. The first time, the nurse laughed because she said such a low-dose of Mirtazapine could never do this. The second time, the doctor I saw said Mirtazapine can produce vicious withdrawals and I tend to be extremely sensitive to medication anyway.
Currently trying Niacin (3g a day) and Manganese (20mg-30mg of chelate a day), with some very slight results possibly.
I took 25mg of Lithium Orotate out of desperation last night and it helped a lot of the physical anxiety and let me sleep, but made the restless legs worse.
Other clue: Melatonin pretty much fixes the issue when taken at night (though I ran out).
On top of everything else that sucks in my life, I get to miss New Years now because I'm too restless to leave the house. I can watch 5-10 minute clips on youtube, but nothing else.
My own GP said he has no ideas either, and is a 45 minute drive away ..
I thought about Lyrica.. ?
