liver cleanse?

I suspect I need to cleanse my liver.
My long standing problem was craving sweets, particularly chocolate and not too sweet cookies... otherwise I'm vegetarian with mostly healthy food diet.
Lately I've noticed that even after small amount of food I would feel some sort of discomfort. I've been happily eating grapefruits for breakfast, but recently was finding very hard to enjoy them. Drinking warm water with fresh lemon juice first thing in the morning became a very of putting thing too. I can't stand the sourness.
Last week, from about 9 days before my period,I felt angry. Minor things would irritate me and I'ld stress out about smallest things. No obvious reason for anger, maybe just angry with myself, for not finding will power to improve my eating habits and stick to good things (like more exercising & positive thinking). I've started to feel occasional dull discomfort on the right side, liver area. Sometimes it would be stinging, sometimes just annoying feeling, but no pain or tention on examining the area. Also felt it's more noticeable in the evenings. I also have strange metallic/bitter taste in my mouth. Some food tastes bitter. The taste is not constant. I've far less apetite.
I also noticed I got breathless far quicker... I've started running in the mornings and had to stop far more often than normally.
Noticed I get this burning sensation under my ribs and solar plexus, especially after tea (herbal, I do not drink caffein drinks) and fresh vegetable or vegetable & fruit juices. Like I had first food today - my freshly prepared carrot juice with super greens powder about 45min ago, still have bitter taste in mouth and felt some mild burning in stomach & solar plexus area. Gastric ulcer?

I took Lycopodium 30, about 7days ago for 2 days (morning and evening). Stopped when my period started 3 days ago. My anger is gone.
I would like to battle my sweet cravings for good, so am looking at some lifestyle changes and would want to cleanse my liver.
I don't think I can do the liver flush with oil and lemon juice, as I can't stand lemons at the moment. But would try the apple juice fasting for 3 days and then do the liver supporting diet.
Any suggestion to what remedies could be useful for me now?

I'm not liking cold, but always feel better in fresh air. Prefere warm food and drinks, no thirst, like carbohydrates, dislike citrus. I feel better for consolation, after sleep and am afraid to eat...

Thanks!
