Depends on what strength they are ( mg)
Effects? If you have anxiety you'll feel relaxed and calm
Me? They put me to sleep. Benzos for me aren't recreational. But I don't have anxiety issues.
If you are going to take the 2mg xanax bars that you have available, being benzo naive I would start with a quarter of one bar which is .5mg. Do not drink any amount of alcohol. .5 mg will relieve all anxiety and you can make an assessment from that point if it helps and if it does I highly recommend you go to a doctor regarding treatment for your anxiety, if you are going to continue taking xanax it's best you actually see a doctor and are prescribed it for many reasons.
