What are some good PRN meds to augment monotherapy with lamotrigine in times of extra stress, such as when traveling? I know from past experience that stress is a major trigger for my episodes, especially when combined with sleep disturbances. My main goal is to prevent relapsing into depression in times when I can't avoid stress or sleep disturbances. I'm not yet certain whether the lamotrigine alone will be enough in those cases.

I'm definitely thinking something like lorazepam to counteract jetlag when I have to travel, but what else? Seroquel has been a relatively effective mood stabilizer for me in the past, and I suppose I could temporarily start it up again when I anticipate a time of stress, but if possible I would prefer something with fewer side-effects. Any recommendations? This thread is about meds but I do plan to use psychotherapy and non-medicinal coping methods as well, and of course to minimize stress in the first place.
