Yes, I think you may need more time. Everyone is different. When I went from 6 mg of [...] by pills to 5 mg of [...] by pills and 1 mg of [...] by liquid, it took me like 3 or 4 weeks before my body adjusted. Then I switched over to 4 mg of [...] by pills and 2 mg of [...] by liquid and barely felt it.
It has been worth it to allow me to micro taper, or at least make much smaller cuts than I could accurately do by splitting 2 mg pills in quarters.
