What has 3 protons, 4 or 3 neutrons, 2 electrons and the potential to poison you?

 Well, I saw the doctor. He's considering putting me on lithium (couldn't do it there and then because it needs to be started in hospital - bigger undertaking than valproate or carbamazepine). Fun.

Also Will dropped by to check up on mefor a surprise visit last night. Fun (not sarcastic this time though). :)
