Anxiety Adventures #12: Back to Square One?

It's been almost a year since I started taking 17.5 mg of Venlafaxine (Effexor) for my anxiety, and at first it was great-- it seemed to really help a lot. Then it didn't anymore. About 6 months in, I talked to my doc and she suggested increasing the dosage to 37.5 mg, so I went with that. 6 more months have passed and guess what? Yep. Tolerance, so it's not working anymore.
