Hi, I am experiencing a drunkeness feeling and nausea when I lie down in bed at night. Sometimes during the day I have had dizzy spells too but not for a while. When I was younger I used to have blackouts, after speaking to a lady I met today at a hospital visit for something else, we got talking and she told me she had experienced these exact same things, and she only found out by chance after having investigations for something else that she has a brain tumour. My sister has also had a brain tumour. I am worried about this, can you help?
