I found that my attacks were brought on my a combo of stress (huge!!!! ), not drinking enough water, and eating a large meal late in the evening with lots of salad and dairy fats, my favorite combo. Too hard to digest. Under advice of a naturopath I take lecithin, vitamin C, fish oil, and GB 6 which is a chinese herb blend. I ditched dairy and coffee and drink green tea, which is a calmative, and I have been symptom and pain free for a year. And, I'm healthier than I've been in ages. My GB was the canary in the coal mine for me. I find that stress really triggers spasms. If I feel spasms coming on, I sip a little cider vinegar in juice, and I take a percocet which my primary doc prescribed in case of attack. In addition to helping with the sudden onset of debilitating pain, it has muscle relaxing properties that can help calm the spasming before it gets full-blown.
