I have been taking 50mg 4 x per day for about 14 months. I take 2 in the AM and then about 6 hours later take another two - this was the dosage. For a few months now I feel like I am in a fog, disoriented so I decided to get off. It has been about 24 hrs since last dosage and I am feeling rather anxious and still a little disoriented. Any experience the same thing?
