Don't worry too much at the moment hun, give it a bit of time. You should be having weekly blood tests for the first 4 weeks since starting the methotrexate and if the blood results are OK (they keep a close eye on Liver and Kidney functions) then they will ask you to go for monthly blood tests.
I stated on 2.5mg of metho once a week two years ago and I now take 20mgs however the higher dose has allowed me to decrease the prednisolone from 30mgs daily to 7mgs daily. I feel sooo much better it has helped me more than I can say. I would be terrified if they said I had to stop it I have so much faith in it.
Side effects - well what can I say - methotrexate is not for everone it just doesn't agree with some patients and no two people with Lupus are alike.
I found that eating a good breakfast first then taking my metho the whole 20mgs in the morning of one day helps. I only feel a bit nauseous if I take them without food. The other big helper is to make sure you drink plenty of water at least 2 litres a day this help to clear any toxin build up in the body.
I don't know about you but my hair was falling out before I took metho so that aspect didn't bother me so much as long as the bad fatigue went.
As for being sleepy well I make sure that on the day I take the metho I have an early night with a good book.
Believe me D it will help you but it does take a bit of time for your body to become adjusted to the metho even up to 3 months so please just be patient and never miss a blood test as the first sign of any problems will show up in the results.
I also take 5mgs of Folic Acid every day except the day I take the metho and these really help with any side effects. (makes your hair and nails nice as well
I also take Plaquenil, Prednisolone and Warfarin all help together and I think I would be much worse off if I didn't take them. I know that if I miss a day then I feel ill for the rest of the week in particular the pred.
Hope my answer gives you a bit of hope but please remember that their are a small percentage of patients that are not able to tolerate methotrexate so if you are not sure then go to see you doctor. Don't stop any tablets abruptly even if you think they are not doing you any good speak to you doc first.
