For two weeks of every month, I am a normal human.
For the two weeks post fertility-pre period I am a horrible human being. It is stopping me doing things. I am absolutely at the end of my rope with myself.
I just growled at my three DDs, switched off the programme they were watching and told them to go away. For no reason.
I am also constantly hungry during these two weeks.
I'm otherwise healthy, not on any hormonal contraceptions, my cycles are just ridiculously intense. When I'm fertile my libido is stupidly high (not helped by being single!), PMT is turning me into an evil monster, I'm always so thankful when my period arrives as I am normal again for a while!
Really hard to give up in the weeks immediately prior to AF though, so I'd suggest leaving it until after your period and then going cold turkey. Cut out all refined sugar, white bread and processed food. Some people find they need to cut out fruit too but I never have.
It's not too strong to say it changed my life (and Dh's and Dc's lives)
It's really hard for the first few days, you need to keep very busy, but after 10 days or so I found I really didn't want the sugar anymore.
I think with the low carb thing, yy to cutting right down on the white and processed carbs (potatoes, rice, pasta, bread) - they basically behave the same way as sugar once digested - but have lentils, chickpeas, beans, quinoa, sweet potato instead.
I have the same problem but with agonisingly sore breasts and period pains for those two weeks too. Tis hell! I run about 30 miles a week so in my case exercise is not helping, I have tried evening primrose oil and vitamin B but that didn't work for me. Sorry I have nothing helpful to suggest lucy but I am marking my place to see if there is anything as well as Agnus Castus suggested.
