If I understand you correctly you have used hardly any of the med, 1 mg less than once a month.
If I read your post right it does not seem to me to be a rebound effect.
Stopping the drug suddenly can worsen your condition and cause withdrawal symptoms (anxiousness, sleeplessness, and irritability). Your doctor probably will decrease your dose gradually. Reference: Pocket Guide PDR, 7th addition.
I understand this to mean a regular daily dosing regime.
I would talk with your prescribing physician on how you should be using the medication.
