two girls mom...I have the same thing, except mine only happens when I wake up first thing in the morning. do you have it other times during the day too and did you have it before going on the effexor? I'm not on any medication, just a small .25mg of clonazepam every night...my doctor said it could be that my hormones are extra sensitive to my body's "wake up chemicals"...also has anyone noticed that after going off yasmin your sleep cycle is different? I wake up every morning now between 7 and 8 am...I'm a college student and used to sleep till 11 or 12 on the weekends.
