Side effects while on and off zoloft?

I had been on Zoloft for maybe 2 weeks, but then i noticed that i would get horrible off and on nausea, diarrhea, constipation, and headaches. So, the nurse told me to just quit taking it. Ive done so. Now, ive been having those electrical impulses, and i woke up with a bad headache this morning along with severe gas. so then just a couple minutes ago, i took half a zoloft, which was what i was originally on for the first three days i took it. Its 50mg. What should i do to balance myself out again and feel normal physically?

To feel normal again, do this pranayam everyday, twice a day.Come back to report your progress after 9 days, but continue the pranayam.
Build up your timing gradually.If you feel tired or dizzy, stop and resume after one minute.
