Ryask, if you feel happy, then thats all that matters, everyone in the world has to sacrifice something for happiness. For you its being a bit irritable sometimes and less sleep! But hey your happy! and thats brilliant manufactured or not.
And i think even the most normal of people need to manufacture their own happiness most of the time, not many people are lucky enough to be naturally happy.
But yeah Citalopram took me past Hypomania. Not good.
And my doctor prescribed me some other medication which was not to be used with an SSRI, and it basically sent me into a state where i felt drunk all the time, not able to stay awake but not able to sleep either and really confused! And i didnt know what was going on!!
