Please help. I started sertraline yesterday, (for depression & PTSD), 25 mg, and I've had bubbly guts, bloating, and cramping. I'm hoping these are "starter" side effects that decrease with time. Has anybody experienced these side effects, and can you tell me how long it took for them to subside? I really want to stick it out with sertraline until I can feel the psychological benefits. Bad side effects usually make me throw in the towel immediately.
