Good luck in your journey! There's a bunch of documented side effects. Constipation is the biggest one, imho. When going up in doses, many say nausea comes too. You'll get more tired, most likely because of the lower calorie intake. Watch out your blood sugar, if you feel too tired/dizzy etc eat something.
Stay ahead of constipation if that starts happening. Drink a ton of water. I take metamucil 2x day but I'm switching to magnesium to improve a bit.
Be patient with your body. Take before/after photos. Measure with measuring tape at least once monthly. Get a renpho smart scale (~$20) if you don't have one. All this is cool to track true progress, sometimes is NOT the weight were you see the change.
One final thought, my personal take: don't rush through doses. Stay as low as possible. Many don't get results in those and if you do get stuck (4 weeks without losing) or your hunger suppression is not too high is ok to go up. But don't go up if you are getting good results in the dose you are, just because the protocol says you go 2.5 > 5 > 7.5 > 10 etc. Reason is: you can always go up later when you get stuck, but once you go up, the side effects increase and there's a time that you will have no runway left. Some people stay in lower doses all the time and they are fine some need to go all the way up to 12.5/15 to see changes.
