Hello, Firstly i should tell you that raised blood pressure is dangerous if you have one kidney. However i feel that your high b.p. is due to restlessness. Regarding your problems of sleeplessness, restlessness and racing heart, i think these might be the symptoms of an anxiety disorder. For this yoi should take tablet rivotril 0.5mg every night. This will relieve your anxiety and improve your sleep. I also suggest you to visit your physician to rule out any medical causes for anxiety and sleeplessness. I think you should get an ECG done. Some other tips which you can follow for better sleep are: Avoid day time naps. Dont take heavy meals, tea, coffee at bed time. Dont do vigorous exercise before going to bed. Have good exposure to day-light. Make a regular schedule of going to bed. Hope you find this infor helpful. Thanks.
