If you have GAD, it IS not a good idea to go onto
Cymbalta, it may trigger even worse anxiety. There are alot of other drugs with minimal side effects. Lamactil being one(it's actually an anti seizure med) , it's an atypical mood stabilizer which has also helped some like myself with anixety at higher doses.
Don't be freaked out my the scary side effect of the rash, it only happens 8/100 000, as well if you slowly increase the dose, that pretty much elimenates that chances.
