Sertraline and diarrhea does it stop after a while as increased dose has caused severe problems?

Hi I've just gone up to 100mg on sertraline I myself can tend to be a bit constipated so havnt really found it a problem as yet but only been on the increase a couple of days so maybe I will.I just wondered could you try something like Imodium which you would use with diarriah normally wondered if a small dose may help while your taking this drug I know the side effects can be so harsh particularly at the beginning I experienced really severe headaches however considering how Ill I was with a break down 8 weeks ago with obsessive thoughts depression and anxiety I feel the side affects I've endured have eventually brought me to where I am today not fully recovered but much better.Hope you manage to sort it out and soon start to feel improvements .
