Dont skip days. You'll have symptoms every other day because of the short half life of the drug. Better to take out beads so you have a consistent dosage.
The storage in fatty tissues theory seems correct to me. Also I've heard many people say that the withdrawal symptoms are greater the closer you get to the end, with the smaller doses. I don't have any answers but the only thing to do is to become very aware of your body and also develop a lot of patience and self empathy.
