"i have been taking this medication for about 5 years on and off since my husband passed away suddenly.  it works very well for me no side effects i take it as needed only.  it&#039;s prescribed 0.25 2 x a day as needed.  i take half of that whenever i get anxious and feel my heart racing it stops it right away if i find myself anxious at night i take the other half.  i go days without it as well.  the trick is not to use it all the time.  just knowing i have it helps me relax in case i should need it.  all meds are addicting if taken all the time."
