You obviously aren' t dressing right. TWO:... you need to move or do isometric exercises or pull the bow every half hour or something. AND.... you may still be pulling to much weight. When you' re warm and feeling normal try holding your bow straight out in front of you towards the target at arms length. Draw the bow without having to point it at the sky. Keep it pointed at the target. If you can' t.... you ain' t as tough as you thought you were and should drop the weigh a few more pounds. Just really bad planning on this one.
