Fantasic "side effect" in lower appetite

Posted by 4674077201620800439 on May 08, 2016

Apart from actually sleeping better and becoming more relaxed yet focused I noticed having very little appetite once I started taking these. Not in an unhealthy not wanting to eat way or anything - my body simple switched from wanting carbs or guilty pleasure foods (like it used to for 30 years) to calmly opting for veggies. One small notice - the first three days of use were very sleepy, but yet again in a natural relaxed way (not when you skip a good night sleep and feel groggy).

I bought 2 bottles of this to help me sleep better, but i also was using aromatherapy so i am uncertain if this is the main cause of me sleeping better or it's the lavender... I did however notice that it CAN make you unable to sleep sometimes. Luckily it doesn't happen often. I guess i will stick to taking melatonin instead to help with my sleep. I do also take it to elevate my moods (when i am nervous/anxious) and i'll give this one a "plausible" for that use. I will however say that my overall moods are better so i will continue to take it to monitor what it does.
