"took this pill for 3 months now, it was effective for regulating my irregular cycle and did a good job on clearing up any skin acne . however it took me several months to figure out why i was suffering from insomnia . i when taking this pill i had feelings of anxiety and such horrible insomnia i would wake up at night an hour into sleeping and just never go back to sleep. my heart would pound, i was sweating, it wasn&#039;t until i started marking on my calendar what days i had insomnia and saw a distinct pattern and realized it must be my birth control pill. i saw my doctor who let me know that what i was experiencing is called anxiety attacks. i&#039;ve never had anxiety didn&#039;t even know what an anxiety attack was but this side effect is debilitating"
