So I'm on day 4 now, day 1 and 2 were fine only minor headaches and couldn't understand why people said they felt horrible in the first few days. Then, I felt fine yesterday but last night I was so thirsty and no matter how much I drank my mouth was so dry. My stomach was also gassy with trapped wind and I felt awful. Today I woke up feeling so much better but I've gone out today and I'm feeling so rubbish, I'm so tired, my stomach hurts, and im so confused cus I thought I should be feeling better by day 4?? I'm thinking now that my few days of hell have been prolonged and are starting today? has anyone got any advice? Cus I felt fine and now I feel awful and yet out of all posts I've read on here I've not found any which say that someone else felt fine and then started feeling awful after a few days - any advice
