Hi Susan,
Here is some information about Ativan here. Below is an excerpt:
"This medication may cause dependence, especially if it has been used regularly for an extended time (more than 1-4 weeks), if it has been used in high doses, or if you have a history of alcoholism, drug abuse, or personality disorder. In such cases, if you suddenly stop this drug, withdrawal reactions may occur. Such reactions can include seizures, trouble sleeping, mental/mood changes, increased reactions to noise/touch/light, nausea, vomiting, diarrhea, loss of appetite, stomach pain, hallucinations, numbness/tingling of arms and legs, muscle pain, fast heartbeat, short-term memory loss, and very high fever. Report any such reactions to your doctor immediately. "
You could be experiencing withdrawal symptoms, but the best person to ask is your doctor. I hope this helps. Stay in touch and let us know how you are doing!Vicki M
