Silent/Acephalgic Migraines Sufferers?

Hi! I've been getting silent migraines regularly for almost 4 years. It's hard to find information and advice on these since they are less common, but they are still incredibly debilitating, and I frequently have to miss work, class, or social events because of them. I was wondering if my symptoms are similar to others of you who deal with these migraines, and what you have done to help decrease them or deal with the symptoms. Some more details... - I first got this migraine when I was 17, and I was diagnosed after the doctor eliminated other possibilities. - I have never had a migraine with headache. - I used to get these every 1 to 2 months, and now I get them every 2 to 3 months. They seem to be relatively hormonal, and I usually get them in the PMS stage of my cycle. - They usually kick off with a day of feeling tired, nauseated, fuzzy-headed, dizzy, and cranky with a mild tension headache. This usually peaks with some physical symptoms, most notably muscle weakness, which makes it difficult for me to walk, move my arms, or grasp things. I usually also have slurred speech and slow thinking. This is what generally keeps me stuck at home, and it lasts for most of a day, and makes me very fatigued for the following day. - My triggers are usually stress or loud sounds. I am also very sound sensitive during the migraine. - The only thing that definitively works is sleeping it off and waiting. Eating something carb heavy sometimes helps lessen the symptoms for an hour or so. - My mom recommended evening primrose oil supplements, as they helped her migraines (with headache). This seems to make them less frequent, but doesn't stop them. - I've tried a diet (I can't remember the name, but it basically cuts out most fermented foods) but it didn't seem to help. I don't think my triggers are food based. I'm so tired of dealing with these and having them interrupt my life. Has anyone experienced something similar? What worked? Do you recommend any OTC meds for the muscle weakness? Thank you so much!
