Hi Ashlea, I was on 15mg for a week and went up to 30mg and for me, yes I am always tired or drained, and I am still eating so it's not fatigue from lack of food. Things should settle down a bit. All the best
Yes, it's pretty normal to feel hungry during the first days. Let it pass a week and make sure you have at least 3 meals (small ones, a fruit or something even if you don't want to eat), small meals combined with lots of water bring you energy but you still keep losing weight. Plus it will solve your tiredness problem. Good luck!
