I've realised that I didn't take my 20mg metotrexate the week before last week, so this means I have now gone 3 weeks without. I have been on anti-biotics and anti-microbials for lump I won't say where! I have started noticing that my joints are starting to hurt and I feel a little stiff on a morning when getting up. I was having a sleep after my night shift (last night), I woke to about 11am this morning and nearly took a nose dive on the floor, I've not had that before. Not sure why, plus I've also stopped taking codeine phosphate as I don't want to be too dependent on them. I am close to finishing the Gabapentin. Could this be why?
