Interesting option of meds. Gabapentin is an anti-convulsant that is sometimes used for neuropathic pain. Cymbalta is an SNRI anti-depressant.

I've been taking gabapentin for 15 years but do not see any benefits for symptoms like you mention.

It is an easy med for most with minimal risk of side-effects. It would be simple to try to see if you get any benefit.

Before trying the Cymbalta with its side-effects, I'd suggest reading the Vitamins sticky at the top and getting on a brain nutrition regimen. You could add 5-HTP and even L-Theanine. They are more natural at addressing some of the same symptoms as an SSRI or SNRI.

What are you doing to avoid the triggers you mentioned ?
