I had the shakes so bad i had to drink with a straw because i couldn't hold a cup to my lips. This was usually around days 3-6. I don't think i could reliably write for the first couple of weeks. I found my hand shaking on occasion for the first month or so. Since you're experiencing the shakes, you may want to check in with a doctor. It's always good to get your doctor on board with your sobriety.
