I was just put on this medicine yesterday 7/31/13 after being unsuccessful with vesicare. I was reading as much info as I could about the drug.Some of the side effect have me worried. Will this drug keep me up or put me to sleep. I'm a lil concern because I have a hard time sleeping, but my doctor soIved that by having me take my migraine and antidepresssion meds at night cause they make me drowsy. I also have trouble w/ my bowl and I take a prescribed med daily to keep me regular. My doctor said I could take it anytime. I would Like to know your opinion. Thx
