I started 3 weeks ago on 15mg and slept great also but still had bad days with anxiety on and off. Three day ago I went upto 30mg as agreed with DR and am sleeping even better which was a surprise as I was expecting to not sleep so well on 30mg. I still get bad days and think this is the way it will be so don't expect too much and your only 5 days in so the drug wont start to kick in yet it's far to early. Be patient and expect bad days and good they are going to happen no matter what drug your on. Keep a diary so you can look back then you can see when things start to get better.
