I saw your posts yesterday, but didn't feel I should comment.
Now you have asked, i think I can say that i am very worried for you.
Reducing all your meds, especially when so vulnerable, is a very serious thing to do.
I understand completely why you feel scared of running out, but the chances are this will not happen.
Venlafaxine needs a very very slow taper. Please don't google it, just trust me on that.
Try and stay positive. You have a few avenues for getting your meds. I think your wife will get them to you, as usual, just later than expected.
