birth control
"I began taking Tri-Nessa 2 months ago and have already experienced 2 week periods, beginning in the middle of the second day of the 3rd week (too early), insomnia (I have NEVER had a problem sleeping), a feeling of aimlessness, overwhelm, and unexplained sadness and irritability.  I had asked for Ortho Tri-Cyclen as I had had no problems at all with it, but was given Tri-Nessa with the explanation that they are the same but unfortunately they are quite different."
