Dear Welcome to HCM We understand your concerns I went through your description. I suggest you not to worry much. As your neurologist can t find anything wrong with you, then, in my view it is very clear that you are a victim of laziness and negative thinking. I presume that you had made it a habit to sit idle and think negative. Naturally, when we sit idle, lazy, there is every possibility that we get dizzy, rather sleepy. That sleepiness, over prolonged period, makes you to doubt that you have dizziness. You must understand that Idle mind is devil s workshop . Work, work and work. You will make it a habit and the dizziness should go. You might need psychotherapy and other cognitive behavioral therapies. I can help you through telephone. Please do contact me through customer care of www.healthcaremagic.com for a telephonic consultation session. Hope this answers your query. Available for further clarifications. Good luck.
