depression
"I have been taking sertraline for quite some time now (over a year) 100mg. Pros have been that I have been a lot calmer, not having panic attacks and less weepy and anxious. Unfortunately there have been some side effects which wont go away - I suffer from headaches a lot, extreme tiredness (am tired all the time - despite having 8  hrs sleep, etc.), I have no desire for sex and I have gained weight (though suspect the weight gain is more down to the tiredness and me attempting to get energy through food). On the whole though I'm happy with it."
