Sides are really fading but I have a little warning for the new minoxidil users: if you come home drunk go easy on the minoxidil, sides seem to kick in harder when drunk.
I was dizzy and tired after I applied 2% as well. I kept it up but after a few days I had the swollen face and eyes as well as a rash over my face neck and chest. I tried to keep going in the hope that I would get used to it but it just got worse. I guess I can't take minoxidil. It sucks, trust me.
