Lavender is awsome, i recommend that too. i wear it daily as a perfume oil to keep me calm. diet is a big factor, eat tonns more fruit and veges, i have found one moring i woke up really really angry after eating fruit and veg for a few weeks straight, the night before, i ate beef, thats why i woke up so angry....grumpy, felt like blah.
make sure you get your body clock set right, every morning when you body gets hit by sunlight, your whole body including its organs reset their internal clock. this happens every single day and night. They never stop ticking. so if you work odd hours, your making yrself more sick. so try and work during the day and sleep at night ect. i hope this helps.
cut out caffiene drinks, they do nothing but dehydrate you and give you a false boost. Also look into natural cleanses and flushes...... gall bladder flush, bowel flush ect....... you could have too many toxins built up inside you. most natural flushes are free and can be found on the internet, And you will be amazed at how good flushes make you feel.
and last but not least, make sure your lifestyle isnt too hectic, if it is, you need to make changes, health as a cost, isnt a good cost.
and exercise is great too.
i hope this information is useful to you.....
