What line of work are you in? <a href=" http://www.bramsonwelch.com/generic-imitrex-sumatriptan.pdf#jackson ">what is sumatriptan 25 mg</a> The North, seeing an opening, has been sending weapons secretly to David Yau Yau, a Murle rebel leader with a small force attacking Southern troops, to fuel more conflict, hoping the South will react with military repression, instead of persuasion and negotiation. And it has. The South appears to be blaming the entire Murle tribe for David Yau Yau's treason. The northern strategy of fomenting tribal unrest in the South appears to be working.
