My understanding is, that when you come out of The Hub, the NeoPsion goes back into your inventory and back into your head, but you need to relog for that to take place, and it doesn't cost you anything.
Unless something has changed ... there's only one way (I think) that what you're experiencing happens, and that's if you sign out while in The Hub? Not sure, so someone would need to verify that for me.
Edit:
Lykke got to your post before I did, I had her in Skype and she was going off to rest so I thought I would help with info, but she said basically what I did.
