Interestingly the phenelzine is a more recent discovery than the worst of my depressions but it works on the mild-to-moderate ones, so why not? Am kind of hoping I've grown out of the horrible immobile depressions the same way I seem to have grown out of the horrible agitated depressions (I always used to get those multitrack speeding thoughts and interweaving earworms as a part of an agitated depressive thing, rather than being up and happy like I get now). No wonder they can't decide what the fuck is wrong with me 
I'm glad you managed a nice walk without pain Mitch - it opens up the options available to you for activities while your calf is recuperating, I guess? I only thought of bag work because I know it's incredibly intense cardio with a lot of upper body stuff, but I guess you can't really do it without bouncing around too 
What's the difference between a spin bike and a normal stationary bike?
