Even though you have been on a very small dose of Zoloft, quitting these meds can
be very hard. I'm not completely sure of this because you
didn't feel anything when you cut
your dose in half, but most people feel great at first when they start to stop taking an antidepressant. This is because their brain and body are working naturally again instead of artificially, and the side effects go away. But when the withdrawal starts, it can be really really hard.
