+# Avoiding FLOOD_WAITs
+
+If you make too many requests to telegram, you might get FLOOD_WAITed for a while.  
+To avoid these flood waits, you must calculate the flood wait rate.  
+
+Calculate it by making N of method calls until you get a FLOOD_WAIT_X   
+ 
+```
+floodwaitrate = time it took you to make the method calls + X   
+```
+
+Use sleep to execute max N calls in `floodwaitrate` seconds, this way you won't get flood waited!
