I would think any treatment that helps learn how to relax the specific muscle(s) involved would be helpful. Guided imagery, meditation, yoga, biofeedback, etc., can do this.
Also, chamomile, skullcap, and valarian root are herbs that have relaxing qualities and may be helpful (make sure to check with a pharmacist on drug-herb interactions first if you take any over-the-counter or prescript
ion medications). Don't use valarian or skullcap if you plan to drive/operate machinery - these herbs can be very relaxing and can put you to sleep. Also, the chamomile is cross-reactive with ragweed, so if you are allergic to ragweed you should avoid chamomile.
Magnesium and Calcium supplements may also help - these two minerals are required for proper nerve & muscle function, and an imbalance or deficiency in either of them can lead to muscle spasms and cramps. Make sure you are getting enough of both. If you take supplements of these minerals already, you may need additional supplements during the times that you are dealing with the spasms to help encourage the body to make the spasms stop happening.
And finally, avoid eating food or drinking liquids that are too extreme in temperature. This is a known trigger of esophageal spasms for myself and others.
I hope this helps - take care,
