adhd and pmt related?

Hi there Wondered if anyone could give me advice. I have bad pmt every month, I get these build ups in my stomach where I just want to pop and explode, I either swear at people or want to punch things. I also have ADHD. I don't know if this affects it too and also I have epilepsy. Once the outbursts of anger are released I feel so much better for it but I then realise Ive upset a lot of people. Ive tried taking medication for PMT but as Im epileptic drugs I cannot take any as they cause me to have some aures related to fits. I don't know what to do. The swearing has got out of hand and cannot control it any more. I go to a gym nearly every day and it helps a lot. Any advice, Im 28. Thanks
