ADHD/GAD as a breastfeeding mama! 4 months postpartum medication advice!

I have diagnosed ADHD and GAD, both of which I have been medicated for in the past. I had great success managing my ADHD with 40mg of Vyvanse but had to stop when I got pregnant and while I am currently breastfeeding. I’ve been on 20 mg of Escitalopram (Lexapro) for over 2 years and stayed on it during pregnancy and now while I am breastfeeding.

I am 4 months postpartum and am finding that the Escitalopram is no longer working for my anxiety. All of my previous symptoms have returned. Because I am not currently treating my ADHD, I also feel those symptoms becoming increasingly harder to manage.

My doctor does not recommend going on Vyvanse while breastfeeding but is open to switching me off Escitalopram to something else. She suggested Cymbalta but I’m reading it can lead to weight gain which is my biggest complaint on Escitalopram (I’ve gained 45 lbs since starting it).

Would Wellbutrin be an option that could help my ADHD and anxiety? Should I just try another SSRI or try an SNRI instead?

Any other moms on here who have had to deal with ADHD and or anxiety while breastfeeding?

THANKS in advance!
