Cheilitis After Stopping EPO

Can anyone think of an explanation for this:

I began taking evening primrose oil about 8-10 months ago because I had chin Acne and pms.

It helped those two things, but I began to gain weight in my hips and thighs so I stopped about 2-3 months ago.


Since then I have had three cheilitis incidents. The current one was bothersome enough for me to investigate and diagnose.


My lips are sore and red and swollen.


Also, I've smoke pot on and off since I was fifteen. Lately I haven't been smoking at all. I've stopped in the past with no similar issues.


I am 29 and i haven't had this issue ever before, and I want to stop whatever I am doing to encourage it but I don't want to be forced to take a supplement that kills my libido and makes me fat.
Please help!
