Withdrawal from everyday use

I was wondering at what GPD the withdrawal would start to become significant. I used 20 gpd a few months back and had to stop because i realised the withdrawal was pretty severe. Now I am using again everyday but I stay below the 10 GPD. I only use 3 in the morning and 3 in the evening. So my question is, do people who use moderetly like <10 GPD get withdrawal when the go without it for a couple of days. I would like not to worry about it for when I go on hollydays etc. Thanks for your input :)
