Hi Lacraft I'm having my surgery June 8th and I'm trying to learn everything I can before I go ..so my question is do you take the b12..5000 dissolving tabs along w/ your multi vitamin chewables and would you need the calcium if your doing the multi vitamim..I'm so worried that my body won't get what it needs I'm sure everyone has the same worry going into this,, Glad your doing well nice to here good things from those that have been there,,,,Thank you in advance for all the helpful info I truly appreciate it ,,,,,,Chelsie
