This is how I was Polly, Cit took 12 weeks to work on me @ 40mg.
More bad than good days and motivation and energy the same. This is why I put 3 stone on.
Stick with them Polly they do work, I only swapped to Fluoxetine to get a lift, I then joined a gym and lost 4 kilo's in 2 weeks.
I find that they continue to do there job months later.
