I would like to know what the problem is with antihistamines and coffee. I've been off both now for 3 weeks and for the past week haven't lost any weight. I think it may be due to water retention from my allergies (ragweed this time of year - I am so bloated!) Before I started Atkins (this is the start of my 4th week of induction) I would take zyrtec, benedril, and drink 4-6 cups of coffee so I wouldn't fall asleep.

I've been in ketosis (heavy) since day 4 and have plenty of weight to lose. I feel frustrated! help....
