The instant release formulations work much faster. Common side effects may include: nausea, drowsiness, dizziness and constipation.

I have 2 different kinds left but don't know which ones which!? One has a M on one side and Ms30 on the other. The other one has m on one side and abg or something on the other, both are purple.
