I have been in 100mg of steraline (Zoloft) for 3 months but I had to stop taking it because I was on a birth control that made me incredibly sick for 3 weeks before my weird. I had just taken one last night and woke up this morning feeling very nauseous, shaky, getting cold chills and having slight diarrhea. Should I be concerned or is this normal with retaking a stronger dosage of Zoloft after not taking it for a bit?
