First Time on Zoloft

Only my first day on Zoloft and I've rarely had anxiety so bad. Took it last night at 8PM, didn't sleep at all and then spent the morning throwing up and the whole day on the verge of a panic attack.

I have GAD and I'm concerned by the comments on here that it might take 4 weeks or more of this hell before I feel what I felt before (which was bad anxiety) let alone get better. I've almost drunk alcohol again after being sober for 6 months just to self mediate and feel better.

Is there anyway to manage the side effects because at this point I'm inclined to not even take tonight's second dose? These would be massively increased anxiety, inability to sleep and vomiting. This stuff is rough.
