Tried Mirvaso for First Time and Product Only Lasted 4 Hours!

I am new to this site and I have had Rosacea for about 5 years now. I have struggled to contain and hide this (even denied really having it) but it keeps progressing and getting worse. I have Type 1 with redness in my cheeks that streak down and my nose. I have done lasers in the past with no success, recently my derm gave me Mirvaso as a trial and I am mixed about it. The first night I applied before going out to the bar, it was extremely warm and only served craft beers so naturally my worst nightmare for a full flush. Surprisingly no flush until the end of the night when my right cheek flared up, nothing though compared to what could have been. I had no rebound flushing the next day which was one my major fears using the product. Actually the next day my skin looked better then it usually does after a night of drinking. I felt amazing and couldn't believe this may be the answer I was looking for the past 5 years. I felt bold and put it on before leaving for work at 8am, arriving at work and lasting the morning I was looking great. Around noon I stopped at the bathroom and while washing my hands I noticed the right side of my nose was turning very pink and blotchy (it had only been 4 hrs, this couldn't be right) so I applied a very tiny amount to the area and went about my day. The next 5 hours was awful, my face kept starting to flare and not a normal flush but more red and blotchy. I would have to continue to run and apply more what seemed like every hour. My nose seemed to actually stop responding and stayed a consistent red. Finally I had to get out of there and I made an excuse saying I was sick so I could leave early. I was distraught and depressed, so much hope that I had finally found something that could help and now back to nothing. I got home and upon first look in the mirror my face actually looked good again. I don't know what to do anymore.

What I was told was that this product was supposed to last 12 hours, mine lasted 4 and then either I had to deal with bad flushing or reapplying every hour. Does anyone have any advice or experiences they can share? This worked so well for the first 4 hrs but its not worth the anxiety and distress thereafter. Also has anyone tried a combination of both Laser treatment and Mirvaso? Any advice would be much appreciated. I am so depressed and lost after this experience that I do not know what to do anymore.
