Relapsed and starting again tomorrow

Hi all I relapsed I was off for a month and felt no benefits but I think I know what my issue was . I was strict carnivore that month and my sleep was awful I reintroduced carbs and I'm back whole foods and feel amazing but I also brought back caffeine soon after but the anxiety and sleep is back too ... So I'm keeping carbs this time and no caffeine from tomorrow. Any words of advice this time around or encouragement
