Newbie Here- Methotrexate Toxicity

So glad I found this forum! I am recently dx with RA. I actually also have a crazy rare breast disease (Granulomatous Mastitis) that is thought to be AI, which was my first experience with AI; but of course the snowball effect happened and now here I am. I was dx in February and although I REALLY didn't want to take any medications (I am a bit of a hippie when it comes to health and healing), I finally started Methotrexate in February after weeks of limited mobility. I am allergic to Prednisone, so that was never an option.

Improvement was slow, but somewhat steady. My body would be super pissed and unhappy with the methotrexate, but then adjust just in time for an increase. Was taking folic acid, too. about a week and a half ago I go REALLY sick. Like violently ill, canker sores in my mouth, headaches, dizziness, fatigue....the list goes on. Went in to my rheumatologist with no fever and ends up I had Methotrexate Toxicity! So, now I am detoxing for a couple weeks and then starting back at a lower dose.

BUT, I am SUPER concerned about going back on it. I'm going to devour the threads looking at other natural/alternative supplements.
What I take now and recommended:
Multi-Vit
Tumeric
Vitamin D
Vitamin B 12
Alternative rx to Folic Acid (for better absorption)
Fish Oil

I stick to a gluten free diet, no nightshades, organic. I had been vegan for quite some time, but have recently added in some bone broth and fish (when I can stomach it).

I have terrible trouble sleeping. Loss of appetite. Cannot be in the sun (and I live at the beach) Would love any recommendations for sleep!!

Thanks

Before the toxicity I was increased to 8 pills/week. It was on my 3rd dose at that amount that I got so sick. Now they are going to keep me off for a couple weeks and then try to start back at 6. The problem (I think) is that my weight has decreased. I'm pretty petite to begin with and tend to have weird reactions to adult dosing of medications. But, we weren't see the results with the 6. We have also talked about doing the TNF Inhibitors as a possibility. The idea is that it might address the RA and the Idiopathic Granulomatous Mastitis (IGM).

Super random, but what exactly does your skin do with the sun on MTX?? Mine feels like it is on fire and I break out in terrible rashes, but they are only located on my joints (even the ones that don't see the sun) and all over my face. Crazy!

I had really bad side effects on MTX when I was taking it in pill form. My Doctor switched me to injectibles and since then the only real side effect has been fatigue but even that has gotten much better after being on it at around the 5 month mark it began to get noticeably better.

I take all of the supplements you have listed and have for years and they certainly help especially with my energy level. An elimination diet might also be beneficial to find trigger foods. I avoid corn due to this and it has helped. All that said I am taking Orencia and MTX weekly or I would be one hot mess.
