My wife, Connie, is taking Lorazepam (5mg) four times a day to relieve anxiety. Lately she is experiencing light headedness and shortness of breath. Could this be the problem. She has Parkinsons and recently had 5 or 6 good weeks. This good feeling has almost suddenly stopped. She feels terrible, all over, right after breakfast, lunch and supper (stomach pain, nausea). I answered this reply and as she is now asleep. She takes Lexapro (5mg) in the morning and one late afternoon. In addition she is on Carbidopa/Levadopa 25/100 three times a day and Carbidopa/Levodopa 50/200 twice a day. Any suggestions, H. Hubbard, Thank You!
