After a few days of testing one food an hour, you will become weary of the routine and wish to eat more normally.  It may also occur that you cannot test more than one or two foods a day from the very first day because allergic reactions do not clear quickly enough.  No problem, the testing period can go on at a lower level of intensity for many weeks, trying one new food each morning upon arising.  As you eliminate allergens from your diet one by one, your resting pulse should drop somewhat and it should be easier to discern allergic reactions.  After you have worked through all the items in your normal dietary, it would be wise to retest the foods a second time, breaking your fast with one different test item each morning.  This second testing round may reveal a few more allergic reactions that were obscured by other allergic reactions the first time through.
