Constant lag upon restoring health.

This is the most annoying bug I have had in any video game I have ever played because its so relentless and happens every single time.

While playing the game would do this thing...not autosave lag even though I have that to. Where it would seemingly for no reason lag for a quarter second every second and a half for about a minute. I finally figured out what was causing this....using a provision to restore health....while the provision icon that represents its still in use is doing the whole cycle feature and my health is rising....it constantly lags...I noticed that once the health reached full...even if the provision wasnt done...the lagging would stop. This started after like 10 hours into the game and only seems to get more common now. This is on 360...I will test more today and see if its only provisions...but it nearly ruins the entire game as I now cant get in a fight without having to waste instant health items if I dont wanna deal with lag that makes me get hit.
