Opti fast and headaches..

I'm on day 3 now and yesterday a dull headache started, noticeable mostly when I cough or bend over.. but now it's more pronounced and two advils didn't even touch it. 
I am on day 4 of no caffeine so wasn't sure if it was that or the combo.. oh and all the artificial sweetners I'm consuming now when I've never really had them before except in gum.
OF has 70 grams of aspertame per shake, and then the crystal lite and the splenda I use in my tea... my poor head is screaming.
Did anyone else have a headace while on this?

It's likely the caffeine and sugar/carb withdrawal, it seems like a lot of people go through this on Optifast and I went through it when I did the induction phase of Atkins a few years ago. It's pretty unlikely that it's the artificial sweetners though, they've been safety tested and rarely cause people problems.

 
Yes, the first week was pretty bad for me (both times). I would get migraines something severe. 

It got better for me after week one. 

We had been advised to be caffeine-free 3 months prior to Optifast in order to avoid the caffeine withdrawal headaches......but I still had terrible headaches for about the first week. Carb withdrawal sounds about right....

It gets better....just hang in there.

Good luck!

I found drinking alot of water helped!  Not sure if it was in my head (no pun intended) but once I started drinking more water my headaches went away.  Good luck!!

I cut the caffiene months before Opti. I had bad migraines for about three days at the beginning of opti. It is most likely a withdrawal from caffiene, hunger, body cleansing out all the carbs etc...
Just hang in there it should pass soon.
