Everyone's experience with meds is so different, it's hard to say what would work for you.
It may be possible to increase your Wellbutrin, only with your prescribing doc's say so though.
On the other hand, lamotrigine and bupropion (Wellbutrin) may work well.
My depression is very resistant to treatment. I take Latuda and Wellbutrin for the depression. I wonder if/when I will get either better or less of a response. I am 30 years into treatment and many meds no longer work at all.
Although I am impressed by Latuda (in my own experience), I am very dismayed with the cost. I may have to stop Latuda just because the co-pays are outrageous! (Hundreds of dollars a month for co-pays. Thousands without co-pays/coverage.) What good is a drug if the population in need cannot afford the drug?
Definitely do a good, solid trial of affordable med combinations first!
