Hi - I Have Been On Ativan For Anxiety Almost

Hi - I have been on Ativan for anxiety almost 4 weeks - usually 2 mg per day. I am concerned about addiction and side effects, so trying to start cutting back. Yesterday, I took 1.5 mg total (1 mg AM, .5 mg PM). Had a pretty intense bad nightmare, and some insomnia. Upon waking up this morning, I felt OK. So today, I took .5 mg at 8:30 AM, and then another .5 mg at 2:00 PM. 1 mg total. I was feeling OK today, a little calmer, and thinking maybe I was taking too high a dose previously. So, is it OK if I cut back to 1 MG for a few days and see how it goes? Have read about the risks about cutting back too quickly, but am not sure if this applies to this duration (4 weeks) and dosage. Thanks.
