Thanks for the info guys, I'm going to try 1.25mg every other day to start with since I've got a large batch of 5mg.
This is an interesting article with a topic on reduced dosing if you've not already seen it, plus I'm over 50 so may find the lower dose OK.

Reduced Dosing
Anecdotal evidence has shown that doses of less than 1 mg/day are as effective as 1mg/day. Russell Knudsen may have been the first to report dosing less than 1mg/ day, prescribing rather 1mg three times a week. Bill Parsley often starts patients on ¼ mg per day, a 1mg tablet quartered. I have been using reduced doses for a number of years. I start men who choose to use quartered 5mg finasteride on at most ¼ tab (1.25mg) every other day, which is 2.5mg every three days.
If patients who are 40 years old and older choose Propecia (1mg), they are started on 1mg every other day. Any patient who is overly concerned about side effects are started on a reduced dose. I often recom-mend that patients 50 and older take 1mg Propecia or 1.25mg generic finasteride every third day. If patients experience side effects and are concerned, it is recommended that they reduce their dosage by half or stop the medication altogether. It is puz-zling to me that the dosage reductions described above have not led to complaints of shedding or thinning in patients, some who had taken 1mg finasteride/day for 10 years or more.
