Sertraline, weight and exercise

[applespearsbears]

Hopeful bump.....Does anyone have experience of a similar situation?
Started on 25 mg Setraline six months ago all good has really helped but I've slowly realised that the weight has crept up and up.
I exercise three times a week and count my calories, fat and carb intake.
I am heading towards my late 40's but cycle still regular so....
Did I just take my eye off the ball at Christmas, is it the meds or peri mena?
I've really noticed that I can't seem to get up to the fitness I used to have even 12 months ago and my body feels slow, sluggish.
