What is causing foggy feeling in my head?

Hi. I'm a 24 year old female and I was a drug addict for over than five years.
My life was threatened and my family took me on some anti drug clinic where I stayed for about four months.
After this treatment I have never took anything similar to drug so I'm clean for over that two years now.
But after one problem, another occurred.
After my recovery at the clinic I started to suffer from mild depression.
I was being treated for mild depression those two years and I was taking 35 mg of effexor.
I was good on it and I haven’t suffered from any kind of depression what so ever.
Then when my dose of effexor was upped and that’s when I started to feel weird. I started to suffer from some strange foggy feeling in my head and I was wondering what could cause this kind of symptoms?

I certainly understand what is happening with you and I can tell you that you are not alone.
Many people complained about foggy feeling in the head after taking some antidepressant drugs.
Well, almost every antidepressant drug has one side effect. That is sedation and it occurs only if overdosed.
Your change from 35mg to some higher level is probably caused these foggy sensations.
What you need to do is to contact your doctor and to ask him to make you a program to get off of this drug by taking smaller and smaller doses of it. It is the only way to avoid your blurriness.
Or there is also one more option and that is to look for some another medication with smaller sedation index.
Stay away from sugar or anything that turns to sugar in your body such as pasta and other carbs.
Adopt a program of Positive Thinking and consider meditation or Yoga.
