I Accidentally Took An Extra 150 Mg. Of Wellbutrin XL

I accidentally took an extra 150 mg. of Wellbutrin XL earlier this evening - for a total of 600 mg. today. I called Poison control and they said just don't take my morning dose. I'm having some panic/anxiety, tingling fingers and rapid heartbeat. I have taken it for about 7 years and also take lamictal, zoloft and sertraline to treat Bi-Polar type II. I guess I'm just looking for a little reassurance to back up what they said.
