at 50 mg, the first tab sent me into another dimension for about 28hrs, the 2nd night, I took half tab at bedtime, slept good but still had dizziness in the AM. This is 3rd day and i took half tab twice today. Dizziness is the main problem. At 67, I worry about driving, but I did today. Seem to be more aware of what I'm doing while driving, but still worry about it. Hopefully these side effects will diminish with time. The tremors have lessened some, bit still a long way to go. Hope things get better with each days dosage.
