Hello, I am a 17 year old girl and I started Zoloft a year or so ago. Overall, it seems to work okay, although it does increase my appetite :( and when I haven't taken it for several days, I get electric shock sensations up and down my shoulders, arms, and back. I was also prescribed Wellbutrin several months ago because I still wasn't very motivated while on Zoloft alone, and this combination is working fine for me right now.
