I been using S4 for 3 weeks now . Last night it was impossible to drive. I'm gonna follow the protocol 5 days on 2 off and see what happens. But I can tell you that I went blind for like 3 seconds and it was scary cause I was driving. if it doesn't help then I will stop and try again during summer. I will be working morning. So far results with mk. Lgd. And S4 has been great.
