My first dose if mtx tablets yesterday, previous 10 weeks were injections and I feel soo nauseous. Have had no sleep even though I am exhausted. No energy, horrible taste in mouth, and my hair is thinning. Does the hair thinning really happen that quickly? I didn't have these side effects on injections. Bloods were fine before tablets, only high wbcs - lymphocytes & neuts. Am taking anti nausea tabs but not working. Any advice?
