It is a very common problem. The ssri's inhibits the serotonin uptake in out brains so, in essence we get more of that. However that comes with the price of lowering our dopamin levels...dopamine is our drive/go get it neurotransmitter. So, lower dopamine = less motivation and drive.

The solution would be to find the absolute minimum effective doese AND do a lot of exercise to drive dopamin levels up.

Hope that helps a bit.

Much Love!
