I used to not count my calories either, until I did and saw there was a big difference in what I was eating and what I thought I was eating. Lol.
I haven't felt any sides really, bit of lethargy but not that bad. I haven't checked by bp, but I should. I'm also dividing the doses to 3 times a day. I like it cause this way, reminds me I'm on and so I force myself to eat.
I did a post about my calories consumption, u can check it out and tell me what you think. I'm gonna hit the gym, I'll check in later
