Definitely less than 7 glasses, maybe 4-5. Thank you so much for your opinion 
I will try to get an appointment with different specialist, ask what method she will use, probe etc. and what she thinks about my side effects. How long do you think should it take to clean whole beard/neck area?
What really surprises me, how come the same method give such a different side effects on my skin. From 1st and 2nd specialist is like 0 to 100% redness. Maybe my skin is extra irritated by using the wrong probe and needs “a break”. But I will deffinitely see another specialist just to check my options.
