O/T What do you do/take to increase energy?
I take the OTC B12 pills sub-lingual , 1 pill every day(rather than once per week) per my surgeon. I also get the b12 injection once per month. After I get my injection I always feel better and the sub-lingual pills help keep me feeling normal. After I had my baby my B12 levels dropped when they use to be pretty high before pregnancy.
Low iron can cause tiredness too! Have you had your vitamin levels checked lately? If not, I would do that ASAP. Remember, you can't overdose on B-12 (so maybe try an additional pill a day), but you can overdose on Iron, so I would make sure to have at least that checked before you add a supplement. Good luck!
