Greetings... been checking in on this post and glad to see you and your H have been successful in corralling your situation before it could spiral out of control. Balance is no doubt easier to maintain than achieve. Seems as if your presence keeps your H grounded, and when you are away there is not enough" Yin to complement his Yang" so to speak.
About the meds, IMO it has to be frustrating to know what works best for you but have to settle for a comparable script because of pricing/coverage. A friend of ours had the same problem coincidently with her Lexapro script not being covered and was not 100% while she was not able to continue her regimen. The next time I see her I will ask how she was able to fix her situation as she now is back on Lexapro and feeling more herself again.
Don't let it get you down, though, just use a little of that "H" (ad..."H"...d...) and research your options.

Peace to you
