One of the remedies I've been using to help with the side effects of kicking this, interestingly enough, is medicinal cannabis edibles, which has also helped with a gastroenterological problem I have.
What I've often heard is a good route is a couple of tablets of prozac. The half life is on the order of weeks, and so you can take these for a few days, instead of the venlafaxine, or maybe with (whatever your doc says).
Then, after building some up in your system, you can just stop. As you go through the half life decay, it's a built in taper, and it's slow enough to limit side effects.
Naturally don't take my word for it, talk to a doc.
I've considered it myself, because if I miss a dose of venlafaxine, I get terrible vertigo. really bad. But I do suffer from an anxiety disorder and it definitely has made a difference in my life.
Thanks for your reply :)
