First things first, even though I don't care much about how a product tastes as long as it works, this one tastes really good!
A couple of minutes after ingestion I felt warmth and tingling going through my arms. The tingling lasted a few seconds starting from shoulders and going down to palms. The warmth lasted maybe a minute and was mostly concentrated around the base of my neck.
It wasn't anything worrying just a nice warm/tingling feeling that went way.
With regards to sleep, I went to bed earlier than usual as I wanted to test the product in the best possible way. I slept pretty fast but could feel I was restless. I woke up as usual at 04:30 for gym however wasn't in the mood for much. I was hoping to wake up refreshed and ready to smash the weights nevertheless I attribute this to yesterday's workout and that lately I've been feeling more tired, guess it's just one of those days...
I will update the Fitbit later today and will see how my sleep was. Time asleep 7hr 35min (record time
), 2 times awake, 17 times restless & 35min total time awake/restless.
Perhaps it will get better, we'll see.
