Reload Function Being Called Multiple Times

So I've been trying to implement an Assault Rifle into the game I am making. Everything works fine, except for the reload function. For some odd reason, the reload function gets called multiple times (around 5 times per button press I think). Please Help!

 var soundDraw : AudioClip;
 var soundFire : AudioClip;
 var soundClipIn : AudioClip;
 var soundClipOut : AudioClip;
 var mainCamera : Camera;
 var crosshairTexture : Texture2D;
 var ammo = 20;
 var maxAmmo = 20;
 var reloadAmmo = 20;
 var clip = 100;
 var Effect : Transform;
 var TheDammage = 100;
 var ammotext : GUIText;
 var noAmmo : GUIText;
 var antiSpam = true;
 var bulletTex : GameObject;
 var fireRate : float = 0.2;
 private var nextFire : float = 0.0;
 
 function Start() {
 Draw();
 }
 
 function Update () {
 
 if(ammo == 0 && antiSpam == true && clip > 0) {
 Reload();
 antiSpam = false;
 }
 
 Screen.showCursor = false;
 
 reloadAmmo = maxAmmo - ammo;
 
 if(clip < maxAmmo && clip <= reloadAmmo)
 reloadAmmo = clip;
 
 audio.pitch = Time.timeScale;
 
 if(Input.GetMouseButton(0) && ammo > 0 && Time.time > nextFire) {
 nextFire = Time.time + fireRate;
 audio.Stop();
 audio.PlayOneShot(soundFire);
 animation.Stop();
 animation.Play("Fire");
 Fire();
 ammo -= 1;
 }
 
 if(Input.GetMouseButton(1)){
 
 mainCamera.fieldOfView -= 40 * Time.deltaTime/0.3;
 
 if(mainCamera.fieldOfView < 40){
 
 mainCamera.fieldOfView = 40;
 
 }
 
 
 } else {
 
 mainCamera.fieldOfView += 60 * Time.deltaTime/0.5;
 
 if(mainCamera.fieldOfView > 60){
 
 mainCamera.fieldOfView = 60;
 
 }
 
 }
 
 if(Input.GetKeyDown("r") && ammo < 20 && clip >= 1 && antiSpam == true) {
 antiSpam = false;
 Reload();
     }
 
 }
 
 function Reload () {
 
 Debug.Log("Called");
 
 animation.CrossFade("Reload");
 
 yield WaitForSeconds (1.1);
 
 audio.PlayOneShot(soundClipOut);
 
 yield WaitForSeconds(.217);
 
 ammo = ammo + reloadAmmo;
 clip = clip - reloadAmmo;
 antiSpam = true;
 audio.Stop();
 audio.PlayOneShot(soundClipIn);
 
 }
 
 function Draw () {
 
 animation.CrossFade("TakeOut");
 
 audio.PlayOneShot(soundDraw);
 
 }
 
 function OnGUI () {
 
 if(mainCamera.fieldOfView <= 45){
 
 GUI.DrawTexture (Rect(Screen.width/2 - 32/2, Screen.height/2 - 32/2, 32, 32), crosshairTexture);
 
 } else {
 
 GUI.DrawTexture (Rect(Screen.width/2 - 24/2, Screen.height/2 - 24/2, 24, 24), crosshairTexture);
 
 }
 ammotext.text = ammo+"|"+clip;
 if(clip == 0 && ammo == 0) {
 noAmmo.text = "No Ammo";
     }
 else {
 noAmmo.text = " ";
     }
 }
 
 function Fire() {
 var hit : RaycastHit;
 var ray : Ray = Camera.main.ScreenPointToRay(Vector3(Screen.width*0.5, Screen.height*0.5, 0));
     
     if (Physics.Raycast (ray, hit, 100) && hit.transform.tag == "Enemy")
         {
         var particleClone = Instantiate(Effect, hit.point, Quaternion.LookRotation(hit.normal));
         Destroy(particleClone.gameObject, 2);
         hit.transform.SendMessage("ApplyDammage", TheDammage, SendMessageOptions.DontRequireReceiver);
         }
     if(Physics.Raycast (ray, hit, 100) && hit.transform.tag == "Land"){
     var bulletHole = Instantiate(bulletTex, hit.point, Quaternion.FromToRotation(Vector3.up, hit.normal));
         }
 }
