Does Daniel have these side effects?

This could be a possiblility.. At the end of the episdoe we see that he has writen in his journal "If anything goes wrong- Desmond Hume is my CONSTANT".... Daniel is aware of the effects... This is also a reason that Daniel and Charlotte performed the card memory trick....Daniel was exposed to radiation/electromagnetic fields from his experiements at Queens College. He wore a protective vest but nothing for his head.
