Hi, I have had axiety for the past two years. I am down to taking only .37mg of Lorazapam daily after a year of continuing a slow & gradual trimming down program to stop taking this drug. Within the past two weeks, I had a very traumatic and stressful confrontation with someone which caused high anxiety and stress. 4 days after this event, I experienced my 1st ever very fast heart palpatations which came on without thinking anything negative and which lasted 20 minutes, or so. I had an EKG which was normal. 3 days after this event, I started to feel light headed with a dazed, spacy feeling and my brain feels a bit foggy. This daily feeling has been on-going for approximately one week. I am taking it easy, continuing my 2-3 times per week exercising at the gym and doing brisk walks twice per week, and doing breathing & muscle relaxing exercises. My blood pressure is within the normal range. My question is, how much longer will these described symptoms last before I return to normal?
