I have a programable shunt. Placed in after it was discovered I have a bilateral CSF leak. As it turns out it was a good thing I did have the programable one since I have had all 5 settings from 1-2.5. As it turns out that right now 1.5 seems perfect for me. If I had not had a programable shunt put in my doctor said he would have had to remove it already (it was put in in oct 2010.) when I was in the hospitial just after its placement I was really sick for days I just vomitted. Once they turned it back down and gave me 2 IVs of caffine my nausea finally subsided. It was definalty overdraining too much and needed to be turned back down. It did get better over time and I am thankful to have a shunt that was able to be programed. In the fall of this year my doctor is thinking of putting in a new one that actually has a shut off valve so I have even more control. Good luck.

Thank you so much for your response. For how long were you sick after they adjusted your shunt down? I was adjusted to 1.5 about 3 weeks ago (the correct setting I was in September 2010 after my surgery) and I am still very sick. I have vomited so much the last 2 days, that I even considered the ER again tonight. Should I give myself a full month to heal again, or is 3 weeks enough time to feel better again. I am not sure if is enough time or not. I am SO GLAD you are feeling and doing so well!
