Bethany began to experience more of a tonic type of seizure in November 2008.  We term these seizures "stucky" ones as she clenches us similar to an infantile spasm, but it is held more continuously rather than as a set of "spasms".  They have thankfully been quite short - only upto 1 minute duration, but over november and december the frequency of these increased and after discussion with the neurologist, we decided to try a new medication - Epilim (Sodium Valporate).
