"i&#039;m 37 and have depression, usually seasonal,  - sleeplessness, and occasional anxiety. 

i took 100 mg of wellbutrin (and nothing else, it replaced zoloft at the time) for around 3-5 days. within 2-3 days i was quite agitated, anxious and easily annoyed.  by day five i stopped taking because i felt hostile and again annoyed.  

cannot speak for others, but this one really made me a monster and i have never, not once, felt like that from any of these:

zoloft
celexa
trazadone"
