Hi there, I am currently reaching my 20 weeks and I having the same issues as you since first trim. I can only eat unhealthy food, junk food, fried stuffs, etc. I try to limit those unhealthy food and reduce it gradually (you can still eat the food you like but limit to 3-4 times a week and gradually reduce to 2-3 times then 1-2 times a week). During your "transition" time, try to eat different variety of food/fruits/drinks by re-introducing them back slowly onto your diet. In the end, I have found out that I am able to eat brown rice, broccoli, curry chicken, soya drink, kiwi, apple and passion fruit. I am still eating unhealthy food 1-2 times per week... but take it slow, explore more variety of food!
