Congratulations, and thanks for reminding me that sometimes it is chemical, and that there's more than one way to find recovery.
It's also a reminder to give things a fair chance to work, or not, including medication and 12-Step programs. One pill is not enough, and one meeting is not enough.
I believe that, as with many things, you have to try it over a longer period of time to really start to know if it's working. I've seen medication and/or 12-step programs work miracles, and I've seen them fail. It's individual. You just keep giving things a fair chance until something works.
Again, congratulations!
