Cyclobenzaprine
"I was prescribed after having neck fusion for neck and shoulder spasms prescribed over a year ago.  I didn't take it but recently started having worsening symptoms that are not managed by alleve and were disrupting my sleep so started taking them. several episodes over the past couple months of indigestion (not common for me).  was only taking once a day but have increased to taking 2x so I can get sleep and function.  no lethargy but have been having horrible nightmares.  also wake up sweating, with extreme fluctuations from cold to hot.  have gained 10 lbs in past month and probably 15 in last 2 1/2 months but it is not listed as a side effect????  not sure how much it is helping and looks like I will have to discuss other alternatives with docto"
