bp*april- please tell us more about this treatment, as I've never heard of it.

For BP depression, my pdoc has suggested I may need to try ECT, but too scared at this stage.

Personally I would not be comfortable in a rehab program; I'd rather go through the detox process at a hospital. The 2 times I've been in hospital, I was in the general ward. The second time I basically just slept for 2 days straight. I had no motivation to do anything else. I cannot comment as to what amount of med combo's is considered excessive, before considering the detox adn starting from scratch.
But especially if u are seeing a new pdoc, he is confused as to to "where to from here" and you really get no relief from your current combo, I would consider a detox to start from scratch.
