Your new neurologist sounds better. The doc that the health food store uses is also starting you good. You might ask to get a B-12 and Folate blood test. Some people do not absorb B-12 orally. Your B-12 should be about 1000, folate 20 or higher, D should be 100 to 150, Hormones also, Thyroid (T3, T4, TSH), Estrone, DHEA, and the female hormones. Good progesterone and estrogen balance will help immensely with moods and outburst behaviors.

You may do better with a sub-lingual or even injected B-12 rather than swallowed.

I have muscle spasms at night so I take Neurontin (gabapentin) 900mgs one hour before bed. It makes a big difference. It is very low in side effects. Without it, I thrash with body jerks and wake my wife and don't get good sleep myself.

Neurontin cannot be taken with magnesium. I take my magnesium in the AM.

Do you have someone who can observe you sleeping? Spasms during sleep can also be caused by sleep apnea. If I sleep on my side, my neck gets inflamed and I stop pulling breaths. It is called Central Sleep Apnea since the Central Nervous System is the cause. I have to sleep on my back and prop my head up with pillows on each side. When I have a episode of CSA, I also have stressful dreams. I will then have a miserable space cadet day.
