Henry, we would also suspect Ativan. After having been permitted by both a GP. and a PD specialist to take up to 5 Ativans per day, along with a variety of other PD medications, (AKA. "the usual suspects"). Heather experienced most of the symptoms, shown in the list from Rita's reply, with the exceptions of, " increased sense of hearing" and "Nausea/vomitting". After finding the same information as Rita, in a drug encyclopedia, Heather went cold turkey the same day. BIG MISTAKE! For the next 30-40 days most of these symptoms were greatly exagerated, and we had a very worrying time. It was a classic case of what we see on this list time and time again. Don't assume that DR's Know about these things; when they are prescribing yet another pill. A second lesson! Wean yourself off offending med. slowly. Today Heather is a changed person, and her friends ask what new cure she's been taking, we tell them it's what she is not taking thats responsible for the change. One interesting aside to all of this is that for the more than a year that Heather was an Ativan junkie, she saw many movie videos and TV programs that she has absolutely no recollection of, consequently we are seeing them all over again. Henry, I know that you will solve this problem if you keep researching the mix of meds. she's taking. Good luck. Peter & Heather
