So far on my first day, I've actually had very few cravings - and I was expecting them to occur every fifteen minutes.
However, for the last 2-3 hours, I've been extremely lightheaded. At one point, I was experiencing a tingling sensation in my left arm, which actually had me Googling to see whether I should be going to the ER or something.
While the tingling has pretty much gone away, I'm still pretty lightheaded or groggy. By way of background, I was pretty restless last night and got literally about 2 hours sleep before a conference call this morning, then I had a nap of about 90 minutes, and then I had another nap of about three hours, so I guess my sleep thing is all messed up - and that might be contributing to the lightheadedness.
Anyway, cravings, not so bad. Lightheadedness, not so good.
