Your symptoms are progressing the way mine have. Started with the tingling, now I have the muscle twitching. I think, though I'm not a doctor, that my twitching is do to my muscles having been tight and contracted for, basically 3 months strait. Now that they are loosing up, they started twitching. It's a build up of some chemical, if I recall correctly. However, the zoloft seems to be working well, as it's keeping me from freaking out over all the twitching. The meds can take up to 6 weeks to work, so give it time. Maybe your doc can give you some xanax until the meds kick in. Exercise has also helped me quite a bit.
