Prevacid and medication

Update: I have been off this medication for 15 days, no problems with stomach acid. I do believe my hair feels thicker as if I am getting some growth where I have loss it. The last side effect I am looking forward to seeing if it is affected, is my Liver tests. The enzymes have always been high (since I started taking this med some 5 to 7 years ago. No matter what I did I could not lower those results, maybe being off this medication will do the trick as I just read last month that one of the side effects are elevated levels in the livers (AST & ALT levels). That can't be good to keep those levels over the recommended zone.

HAIR LOSS....I am a 52 year old male, been on this medication for many years, at least 5. It has worked very well for me and a recent scope indicated no issues in the throat, esophagus or stomach. The side effect I am most concerned about is hair loss. My hair has thinned since I started taking it. No one in my family has a hair loss or thinning issue going back to great Grand Fathers. I am stopping this medication as of today. Does anyone know if hair growth returns after stopping this med?

I've only been on Prevacid for about 2 weeks so I'm not sure if it is the medication or not.

I'm starting to notice some changes in my body since I've been taking this medication. I noticed that during the middle of the night, I'm awaking with a very dry mouth, so now I keep a bottle of water on my nightstand. During the day, I'm catching cramps all over my back and occasionally in my legs. I haven't had any problems with cramps until I developed this stomach condition and had to take this medication.

Could there be a need for vitamin suppliments while taking this medication?
