Not questioning your choices but why skip straight past the normal 2.5 mg starting dose? Even that amount is not yet considered therapeutic. I would move to 2.5 mg and then go up to 5 mg after four weeks.
I began at 1 mg on October 11th to check my reaction to side effects. None appeared so last Saturday I moved to 2 mg, still under the usual starting amount. This week hunger seems to be coming back. After a tuna sandwich I still wanted more food, though I had not eaten much earlier and my total calories were only around 1300. Should I raise the dose next week or add another half milligram sooner?
