"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."
