I usually take my MTX on a Saturday night as advised originally by the doc…this week I forgot! (never done that before…old age I hear you cry) So injected Sunday morning…wow! no crappy sunday afternoon! very tired by bedtime and slept like a log. Felt good Monday too!!! Gonna do the same this week and see if I get the same result 
See, it wasn’t a mistake. It was an opportunity for learning! Glad,you figured it out.
Lol Sybil, you’re kidding!! And…what happened?!
