Creatine..

You would only lose size in terms of water weight, since creatine causes the body to retain water and this will give a more swollen look, at times, but you wouldn't lose strength. Creatine is a great source of energy, so your workouts might be a touch lackluster without certain supplements, like creatine, but it is not extremely dramatic. You should be able to lift the same without it, as the body develops muscle memory, you just have to have an adequate amount of rest and recovery, otherwise you might be wearing down muscle fibers that haven't fully recovered.

You shouldn't be dependant on supplements, but yes creatine is amazing.

Im not sure the OP was talking about water weight.

I just hate creatines

No, its not normal. Creatine is mainly used to make your recovery time quicker. So it shouldnt effect size and any strength issues you may have should only be from your body being tired for longer periods because you arent ingesting the creatine to shorten the recovery time.
