ESA to WRAG appeal effects of morphine medicaton

Apologies if a similar question has been asked before, but I can't seem to find any advise appertaining to my query in recent posts .... so I'm sorry if this is a repeat! I will try and keep this as brief as I can

Sent IB50 Feb and recd reply last wk placing me in WRAG (no medical).

I suffer with painful muscle spasm in my abdomen and lower back, which also causes me to go into urine retention. I also suffer with osteoporosis and osteoarthiritis in my hips, knees, neck, back, feet and hands.

Amongst other meds, I take 120mg of morphine slow release tabs and 15ml/30mg of morphine 4 hrly for breakthrough pain .. a total of 300mg of morphine per day. I have to have someone catheterise me, which can be up to 10 times/24 hrs, as it has to be done laying down, due to me not being able to get into a better position due to the pain. My carer/family do it for me throughout the day and my partner at night and wkends.

Before having to give up my management job, I spent the last 2 yrs in and out of hospital for pain relief and catheterisation (some 20/30 visits). I used to get IB and also after a home visit from DWP (some 5-6 yrs ago) I was awarded high rate mobility and high rate care DLA.

I spend a lot of time in bed, due to the pain and effects of the morphine. My stepdaughter is my carer and my other stepdaughter visits most days and I have two friends that also help with catheterising and day-to-day help etc.

With my IB50 I sent a letter from my GP confirming my conditions and medication and that someone has to carry out the catheterising for me. I also enclosed a letter from my carers detailing what help they provide me with etc and also a copy of my monthly prescription. I sent very comprehensive notes, detailing how my illness effects me and the effects of the high volume of morphine I take, i.e. extreme drowsiness, confusion, lack of concentration etc. I did not exaggerate, just told it as it was.

I feel (like so many, I know) that I should have been put in the support group. I would really struggle to attend WFI's (let alone work) due to the pain and effects of morphine and who is going to carry out my catheterisation should this be necessary? The only option here would be for me to be taken into hospital each time.

My question is, should I appeal or would I just be wasting my time? Also, if I do appeal on what grounds should I base it, i.e. effects of medication, effect if I didn't take it (although that just couldn't be a realistic option).

Thank you for taking the time to read my post and I'm sorry it is so lengthy.
