I've been conscious of the fact that I've needed to reduce my Ped prescription. Gone from 20mg to 3 mg in 18 months. This month I reduced to 3mg and today I feel absolutely rotten, the usual rubbish, pain at the back of the eyes, pain across the shoulders, nausea's and generally no energy at all, just want to lie down. I need some advice as to where I go from here in terms dosage. I was ok at 4mg. Do I go back to 4mg or do I have to start at the beginning at 20mg and taper back down.
