Problems with getting used to a new mouse.

I’ve been using the Corsair Scimitar RGB Pro for nearly 2 years and just today got the Zowie EC2-B. The Corsair mouse had 12 side keys and I used 5 of them (for slot1-5). However, the Zowie mouse only has 2 side keys. Because of this, I’ve had to bind my primary to Q, my secondary to 2, my knife to mouse4, my nades to mouse5 and the bomb to 1.

This has been extremely difficult to get used to and I’ve probably had the worst day of cs that I can imagine.

If anyone has had a similar experience I’d appreciate any advice on how to overcome this problem, and an idea of how long it will take to adapt to this new mouse.
