Hello everyone!
I wanted to help those poor souls like me who find the scroll wheel on the m325 too sensitive with this "fix it yourself" tutorial.
!!! I am not responsible if you void your warranty or destroy your mouse.!!!
So here we go.
There will be no pictures, I don't want any goof out there doing this and breaking his mouse.
1.Never buy a Logitech mouse ever again.
2.The problem with the wheel is not in software settings, the problem is in a Spring that provides tension to a piece of metal that goes against the scroll wheel.
They put a weak Spring and it doesn't push the piece of metal hard enough to the wheel.
Thus our "too sensitive" problem.
To Fix this problem you need to :
1.Open the Battery Compartment of the mouse.
2.Remove the battery and Remove the Sticker that's under it (It's the same color as the body of the mouse).
3.Under the Sticker there's a small screw, you need a Small Screwdriver Star shaped, or you COULD try with the tip of a knife on your own risk.Remove the screw.
4.Grab the upper part of the mouse body and the lower part at the End of the mouse and pull them slowly apart, NOT ALL THE WAY, just enough so you start feeling resistance.At the front of the mouse there are two "Teeth" that hold the two parts together.You don't want breaking those.
5.Now you need to pull them apart, the upper body goes foreword and the lower part backwards.Pull them apart.Slide the body of the mouse foreword and the bottom part backward.
6.After you separate the body of the mouse from the bottom part of the mouse, you will be able to see the mouse Wheel aparatus.The apparatus is attached to the mouse via a piece of plastic in front of it.You can pull it out of the gripping there without problems.
7.Watch out there is a Spring on the bottom of that apparatus!
8.Take a look at the wheel. There's a piece of metallic wire that goes inside it, that wire goes to the back of the wheel and it is kept in place under two plastic teeth.under it is the weak SPRING that pushes the metallic wire UP and by doing so the metallic wire pushes DOWN on the Scroll Wheel and you get resistance!.
9.To fix it, you need some thin part that will go Between the Spring and the Metallic Wire so that Your piece will Push the metallic wire UP and thus provide more tension to the mouse wheel.
10.I had some small scissors laying around so I took and cut one of the tips aprox this long ----, and placed that piece between the Spring and the metallic wire pushing it up.
Make sure that whatever you place there sticks good.
The piece I used is held nice by the Spring pushing it in place.
And that's about it 
In short:
The spring pushes the wire against the wheel of the mouse and that provides tension.
The spring is WEAK and you need to push the wire harder UP so it pushes DOWN on the wheel harder.
To close the mouse, first align the front Teeth with the bottom body of the mouse, then push the bottom foreward and up.
Get the small screw back in place.
And that's it!
Oh and btw, for making me write all that text, and all the troubles with this INSANELY SENSITIVE MOUSE WHEEL, i have a few words for the designers of this mouse.
