Not a silly thread at all. Three weeks ago I started Wellbutrin to counter a low mood and immediately had symptoms like you're describing - increased energy, anxiety, insomnia, etc. I tried to work through the side effects, but eventually had to go off the med this last weekend. Interestingly enough, things haven't yet really returned to baseline. I'm still having anxiety and insomnia, where I didn't deal with these before starting the WB.

Good luck.
