Hi Mish. I haven't had any bad hair issues...I feel like my hair is better because of the folic acid. If anything, I'm just too tired to do much with my hair lol
The side effects are quite individual so I can only share on my experience. I rarely get nausea from the mtx Injections. The pill form definitely did give me bad nausea. I inject in the evening to minimize some side effects. But I do experience what's referred to as a "Methotrexate Hangover" the next day. Basically I feel achy, tired....fluish, really. Sometimes my bathroom frequency increases. I find drinking lots of water helps though..and lots of rest. Sipping gingerale. Tylenol takes a bit of the edge off, though I do have prescription pain killers for my RA pain if I need it. I run fevers as well and honestly, that's the most annoying part for me because the fever just makes me feel even crappier. But I run a fever every day so it's not just a post injection thing.
I know the whole "chemotherapy" part is scary but keep in mind our dosage is a low dose being no where near as high as is given for cancer treatment. Took me a few months to get past that feeling though.
If you do experience nausea, ask for an anti-nauseant. I take Maxeran when needed. Or use your MMJ if you find that helps. I can't do it because I develop paranoia most times and trip out lol
