Does anyone know how long it takes to experience symptoms from the RENU Solution? Ever since I heard about the RENU being taken off shelves b/c people were experiencing problems I've been going crazy with worry. I tried to look up info on it, but it's hard to find what I'm looking for. Does anyone know how long it can take to see symptoms? Is this something I need to worry about a year from now? Five years? Forever? Should I see my eye doctor about it? I've used the RENU solution since 9th grade (the original) and started the Moistureloc months ago (I can't say for sure---somewhere between half a year to a year maybe). I'm now 22 years old. Also, does anyone know if tension headaches are a symptom? I started getting these horrible tension headaches months ago that include forehead contractions (where the muslces in your forehead keep contracting---a symptom of tension headaches I'm told). I have to squint my eyes constantly to try and focus better.

Summarized question: How long does it take to experience symptoms after not taking the RENU solution?
