After taking for just a couple weeks, my appetite went to crap, but mostly, I started to feel like a "crackhead" and my sleep went from six hours, to four hours, then to two. I became sleep deprived, lost weight and actually felt like I was doing crack, even the sniffles. Just yesterday, after calling my doctor, he called in something for me to help sleep (Trazodone 100mg) and I slept for nine hours and felt like I had a hangover. This morning, I only took half of my Zoloft.
